In the last episode (Jan 03), Mirar @ Pike developers forum said:
3.2.1 might not be recommended since it failed to build a Pike now... (Error 139 in pike when making GL/auto.c, says xenofarm.)
You hit a bad 7.5 checkout; take a look at the number of red lights on the last couple builds. I usually get working pike 7.5's on Solaris 7, Tru64 5.1, and FreeBSD 5 with gcc 3.2.1.
