The behavior of this testcase changed last Thursday, in svn r19441. Patrick's patch to compilers/pge/PGE/Exp.pir seems to be the cause. ------------------------------------------------------------------------ r19441 | pmichaud | 2007-06-28 19:14:11 -0700 (Thu, 28 Jun 2007) | 3 lines [pge]: * Remove find_type from PGE/Exp.pir (w/test).

I ran Configure.pl with no arguments. Apparently this test passes on chromatic's linux box, and on particle's win32 box, but fails on my gentoo box and particle's ubuntu box. So its a bit sporadic. I'll post another followup to this ticket if I can find a fix. Mark
