I unfortunately don't have an OSX machine to test on anymore, but I
don't think anyone has seen this previously.  My reading of the
install log (and if you run the script again, you can probably get
away with removing the yt_install.log file) is that the _locale module
failed with this:

*** WARNING: renaming "_locale" since importing it failed:

/Users/millos/visualization/yt/yt-i386/src/Python-2.6.3/build/lib.macosx-10.4-i386-2.6/_locale.so
  Expected in: dynamic lookup

Looking around online, I think this can be fixed with -lintl .  So my
suggestion would be to do this:

cd /Users/millos/visualization/yt/yt-i386/src/Python-2.6.3/
export LDFLAGS=-lintl
export CC=gcc-4.2
export CXX=g++-4.2
./configure --prefix= /Users/millos/visualization/yt/yt-i386/
make 2>&1 | tee build_log
make install 2>&1 | tee -a build_log

and then see if you can do "python 2.6 -c 'import _locale; import locale' "

If not, could you send me build_log?  But, if that works, you should
be able to unset LDFLAGS and re-run the install script (without
removing any of the existing files.)

Thanks,

Matt
