Re: [eigen] Linker error after updating from -betaX to 2.0.0

[Benjamin Schindler <bschindler@xxxxxxxxxxxxxxx>]

Hi

Yes, I intended to use 2.0.0, but due to a misnaming of directories, I
used trunk which was - by an extraordinary coincidence - broken when I
checked it out. Gael already told me on irc (should have mentioned on
the ML, sorry)

Thanks
Benjamin
