[yt-users] installing yt on mac OS bzlib issue

[Andrew Myers]

Hi David,

I'm also running 10.5, and I had this same issue. Changing line 37 of the
install script to

INST_BZLIB=0

seemed to work for me. The comments say something about bzlib being needed
to prevent broken mercurial installations, but that didn't seem to happen
to me.
