[proaudio] Absence / drobilla and fastbreeder ebuilds

[Gavin Pryke <gavinlee303@xxxxxxxxxxxxxx>]

Hi

Having been away for a while I just want to say it's good to see pro-audio 
gain more developers and keep momentum, for a niche project like this it's  
probably hard to find people to maintain such a vast overlay of specialist 
applications. I sincerely appreciate all the effort that everyone puts into 
working on this project and I think maybe we can say that we have one of the 
largest selections of packaged audio apps compared to other Linux 
distributions. The reason I left Mandrake and Red Hat distros way back when 
was because I found I was rolling my own rpm packages for things every time I 
wanted something. With Gentoo and the pro-audio overlay most of it was already 
there.

Anyway, sorry for my inability to respond lately, I've had a lot to deal with 
from health problems and several hardware issues.
I managed to keep the hard drive with Gentoo installed from my computer that 
died and connected it to a rebuilt system, it is a 64-bit CPU but for now I 
will have to keep x86 arch because there is too much invested in it to wipe 
and start over, I wish I had the space to do a fresh install of amd64!

So trying to catch up with things I did a git svn rebase from the proaudio 
repository and tried rebuilding the live svn versions of patchage/ingen and 
all their dependencies from drobilla, I found that all these packages install 
the pkgconfig files in /usr/pkgconfig instead of /usr/lib/pkgconfig and 
patchage fails to find flowcanvas because of this.

$ ls /usr/pkgconfig/
flowcanvas.pc  raul.pc  redlandmm.pc  slv2.pc

I looked into these ebuilds and found that the lines with --libdir= cause this 
problem, removing that parameter from the configure command then puts the 
pkgconfig files in the correct place of /usr/lib/pkgconfig.
I would simply commit a fix for this but I'm not sure how this would impact 
those systems that use 64-bit libs and use /usr/lib64 to store them. Please 
could someone test this on amd64 or another 64-bit arch by changing line 29 in 
x11-libs/flowcanvas-9999 ebuild and others if necessary like so:

-       local myconf="--prefix=/usr --libdir=/usr/$(get_libdir)/"
+       local myconf="--prefix=/usr"

then to test do:
emerge -v1 =slv2-9999 =raul-9999 =flowcanvas-9999 =redlandmm-9999 && emerge -v 
=patchage-9999

If this works then I think we can remove that from the rest of the ebuilds for 
drobilla as currently they are broken for me on x86 unless I made those 
changes. If it doesn't work on 64-bit with these changes then maybe someone 
can shed some light on what's going on here.

Also I've still to catch up of a lot of mail in general and from this list but 
I have some more fixes in other packages and finished an ebuild for 
fastbreeder which I was working on some time ago (I just noticed there was a 
request on the list for this :), it's a bit of a hack but it works for me at 
the moment, will commit those soon.

PS. Sorry for the length and rambling nature of this email.

Cheers
Gavin
