I see. Still, it means under Linux the current situation neither works
well for having both 5.0 and 5.2 installed (I suppose it works if one
is in /usr and the other in /usr/local as pkg-config will output
different -I and -L options). Nor does it work well for the case where
we want a completely transparent upgrade from 5.0 to 5.2 (we'd have to
keep the -5.0 name in 5.2 otherwise users would have to change the
package name).
