Bugzilla Bug 30590

While doing an "emerge -u world" in order to move up to Gnome 2.4, I ran into a
compile problem with dev-perl/XML-LibXML. I am running Gentoo 1.4 on a Gateway
YGR600 laptop with 256MB of RAM and recently went with ACCEPT_KEYWORDS="~x86"
in my make.conf; before using ACCEPT_KEYWORDS="~x86", I had no problems. I did
an "emerge sync" just before "emerge -u world". I get down to XML-LibXML and
get the following warning:

Calculating world dependencies ...done!
>>> emerge (1 of 83) dev-perl/XML-LibXML-1.55 to /
>>> md5 src_uri ;-) XML-LibXML-1.55.tar.gz

    XML::LibXML may fail building or some tests may not pass.

END OF WARNING

"etcat -v libxml2" shows that I have libxml2 version 2.5.11 installed. The
compile begins after the warning listed above and fails with this:

Some Google searching seems to indicate that XML-LibXML-1.55 should work with
libxml2-2.5.11 according to this AxKit thread:
http://www.mail-archive.com/axkit-users@axkit.org/msg04029.html

I can make XML-LibXML-1.56 from source downloaded on CPAN. I still get the
warning about the module version not being tested with libxml2, but it makes,
all make tests succeed, and I can install (but didn't). Instead, I cobbled
together an ebuild for XML-LibXML-1.56 by more or less copying what was in
the 1.55 ebuild. This allowed me to proceed with my "emerge -u world".

Had this exact same problem, version bump to 1.56 with no changes to ebuild
worked perfectly.

1.56 in portage.
