Output of ./configure attached

I am getting compile errors on CentOS 5.7 (at bottom of report) during make of libxslt-1.1.26 with shared libxml2-2.7.8 and zlib1.2.5. Maybe the new libxml is protecting xmlXPathCompExprPtr now? I saw this:

cd ~/libxml2-2.7.8; find . -name "*.h" -exec grep -Hi "xmlXPathFreeCompExpr" {} \;
./elfgcchack.h:#undef xmlXPathFreeCompExpr
./elfgcchack.h:extern __typeof (xmlXPathFreeCompExpr) xmlXPathFreeCompExpr __attribute((alias("xmlXPathFreeCompExpr__internal_alias")));
./elfgcchack.h:#ifndef xmlXPathFreeCompExpr
./elfgcchack.h:extern __typeof (xmlXPathFreeCompExpr) xmlXPathFreeCompExpr__internal_alias __attribute((visibility("hidden")));
./elfgcchack.h:#define xmlXPathFreeCompExpr xmlXPathFreeCompExpr__internal_alias
./include/libxml/xpath.h:                   xmlXPathFreeCompExpr        (xmlXPathCompExprPtr comp);

Just below is how I do the configure(s), make(s) for all my shared libs. I made some notes were I had to fix little things--any use of "env LIBS='-lz'" causes imediate error that is interesting--I use LDLIBS in general and that works, but your help files lead me to LIBS when struggling.

libxml2-2.7.8
-------------
wget ftp://xmlsoft.org/libxml2/libxml2-2.7.8.tar.gz
tar xzf libxml2-2.7.8.tar.gz;  cd libxml2-2.7.8
Edit ./configure.in -- fix 'inttypes.h.h' problem
env CPPFLAGS='-I/opt/zlib1.2.5/lib -I/opt/readline6.2/include' LDFLAGS='-L/opt/zlib1.2.5/lib -L/opt/readline6.2/lib -Wl,-rpath,/opt/libxml2-2.7.8/lib -Wl,-rpath,/opt/zlib1.2.5/lib -Wl,-rpath,/opt/readline6.2/lib' LDLIBS='-lz -lreadline' ./configure --prefix=/opt/libxml2-2.7.8 --with-zlib=/opt/zlib1.2.5 --with-readline=/opt/readline6.2 --with-gnu-ld=yes --enable-ipv6=no --with-minimum=yes 
Edit xmllint.c -- fix #endif /* LIBXML_OUTPUT_ENABLED */ mv down 5 lines
Skip --with-python because it will not compile with 2.6.2 or 2.7.2
make; sudo make install

I have been using the "env CFLAGS='-Os'" to shrink my shared libs when something like the libxml2 --with-minimum=yes isn't around. Will be using python bindings from RPMs because not building on libxml2.
wget http://rpm.eprints.org/RHEL/5/i386/libxml2-python-2.7.8-1.i386.rpm
rpm2cpio ./libxml2-python-2.7.8-1.i386.rpm | cpio -i --make-directories
wget http://rpm.eprints.org/RHEL/5/i386/libxslt-python-1.1.26-1.i386.rpm
rpm2cpio ./libxslt-python-1.1.26-1.i386.rpm | cpio -i --make-directories
cp to my /opt directories.

Thanks for providing these incredible libraries,
Brad
