[xml] libxml on OS X?

[Joe McAlerney <joey SiliconDefense com>]

Has anyone had any luck building libxml 2.3.x on OS X?  I was going to
port an application that uses libxml over to OS X, but have hit a wall
with this one.

[localhost:local/src/libxml2-2.3.13] joe% make
make  all-recursive
Making all in include
Making all in libxml
make[3]: Nothing to be done for `all'.
make[3]: Nothing to be done for `all-am'.
Making all in .
/bin/sh ./libtool --mode=link gcc  -g -O2 -Wall  -o libxml2.la -rpath

make: *** [all-recursive-am] Error 2

The gz undefined symbols obviously occur because the last compile does
not include -lz for whatever reason.  I'm not sure how to resolve the
_main symbol issue.  zlib _does_ exist, in fact, the configure script
finds it's header files and the library itself.  Oh, and gcc is a sym
link to Apple's flavor of gcc (cc).  Hmmm... Well, this isn't mission
critical, I just wanted to know if someone has gone through this before.

Thanks for any help you can provide,
