[igraph] Bug report, building without libxml2

[Asbach, Mark]

Hi there,

I'm just installing the igraph package for a colleague and ran into a small 
glitch: when building from source tarball igraph-0.5.4.tar.gz without libxml2 
present, configure reports correctly, but automake still tries to link the 
library. Building and installing are both fine with libxml2 present, though.

I'm not subscribing to the list, so please CC: me in case of questions.

Best,
Mark
