[Nel] configure and compilation problems on linux

[Michael Warnock]

Greetings,

        I've compiled Nel on Win and Linux many times in the past, but its been 
several months since the last time.  I'm using Gentoo Linux 1.4 now, as opposed 
to Debian previously, but I don't think my problems have anything to do with 
that.  With a fresh CVS (1/20/03), the results of "./configure 
--with-stlport=/usr/local --with-xml-prefix=/usr/include/libxml2/libxml 
--with-xml-exec-prefix=/usr" are:

checking for xml2-config... /usr/bin/xml2-config
checking for libxml - version >= 2.0.0... no
*** Could not run libxml test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means LIBXML was incorrectly 
installed
*** or that you have moved LIBXML since it was installed. In the latter case, 
you
*** may want to edit the xml2-config script: /usr/bin/xml2-config
configure: error: libxml2 must be installed.

and config.log with what I deemed irrelevant removed contains:

configure:7190: checking for xml2-config

        It appears to me that the configure script uses xml2-config improperly 
for whatever reason.  This occurs with the distro's libxml2 and one compiled by 
me from the latest tarball.  Any ideas?
        If I --disable-xmltest configure finishes.  Make seems fine for a 
while, until:

        I hope I've provided enough information and not too much.  Thanks in 
advance for any help rendered.
