I'm having a problem compiling.

I've updated to the latest svn, and ran make TARGET=mess -j4 PTR64=1, like I normally do and I get:

src/osd/sdl/sdl.mak:449: *** commands commence before first target. Stop.

src/osd/sdl/sdl.mak line 449 has
$(error Ubuntu 12.10 detected. Please install the gcc-4.6 and g++-4.6 packages)

I am running Ubuntu 12.10. After installing gcc-4.6 and g++-4.6, it compiles file, so I guess it's just a problem with the Ubuntu 12.10 detection.
