configure script - libsigsegv detection broken?

[Vladimir S. <vs...@gm...>]

Tried building a CLISP I just pulled from CVS, on Debian 5. The installed 
version of libsigsegv didn't work (older version), followed directions to build 
and install libsigsegv-2.8, first with --prefix=/usr/local, then with --prefix=/
usr (default), neither were detected by the ./configure script (passed --with-
libsigsegv-prefix parameter). I think the detection routine is in the 
aclocal.m4 script, but not sure. Can someone double-check this?
