Configure gives this:

checking for perl... /usr/bin/perl
checking for perl >= 5.8.1... 5.8.8
checking for XML::Parser... configure: error: XML::Parser perl module
is required for intltool
make: ***
Error 1

Running the command that configure is running gives:

[wberrier at localhost]$
PERLLIB=/home/wberrier/wa/git/buildroot/output/host/usr/lib/perl perl -e
"require XML::Parser"
Can't load
for module XML::Parser::Expat: libexpat.so.1: cannot open shared object
file: No such file or directory at

This is with an older snapshot of buildroot (2010.02).  I didn't have
this problem when building on ubuntu 11.04, only rhel5.

So, am I correct when guessing the culprit is Expat.so? (missing rpath
to libexpat.so.1)
