[more stuff]

Probably the link on the "downloads" page. It's been a while. Lemme "make
clean ; ./configure --disable-debug --enable-cpu=jitc_x86 --enable-ui=x11
--disable-dependency-tracking ; make" and see if it gets better... nope,
same error. They don't give MD5sums, but is

Never used CVS (the program, not the drug store). Dunno how, but a few
minutes alone with the man page would cure that.

Just tried that. Same error.

"--enable-cpu=generic" is much slower, but gets the same error, with more
info (not that it's any help to me):

Maybe some option I have selected (or not selected) in my kernel?
