[yt-users] gcc compiler option problem during install

[Nathan Goldbaum]

Hey Drummond,

It looks like this is the gcc that comes with the mesa sdk, actually.  The gcc you want to use should be in /usr/bin/.

For what it's worth, we've had issues in the past with people trying to build yt using mesa's compiler toolchain.

Cheers,

Nathan
