That doesn't surprise me.  Debian ran into severe problems with 3.3 with
the official 3.3.0 release when it came out, and the version that Apple
is shipping is a pre-release CVS build.  But then, so was the 3.1 build
that they shipped too.  The C++ front end has had a lot of bugfixing
work done to it for the upcoming 3.3.1 release.

You shouldn't need Autoconf or Automake for visual unless you are
regenerating aclocal.m4, Makefile.in (in any directory except cvisual)
or configure.  Did you need to do that?  The current scripts are
generated with autoconf 2.53 and automake 1.6.  Did you need these
programs for some other purpose?

A note about CFLAGS/CXXFLAGS.  Autoconf automatically sets both of these
variables to "-O2 -g" unless they are already set in the environment. 
So, with these settings, just about any Autoconf-based installation
procedure will build without optimization or debugging symbols.  So, you
will probably want to `setenv CFLAGS "-I/sw/include -O2"` (note the
double quotes) at least, and if you want to provide more useful
bugreports, add -g as well.

Thanks for the feedback,
