Comment 4 for bug 928467

libxslt builds against libgcrypt optionally when available. There are two ways to fix this: pass the --without-crypto option to its configure script, or check if libgcrypt-config can be found and run and add its output to the build libs. I think I prefer the latter. It's always good to support the features that are available on a given system.

Care to provide a patch for buildlibxml.py? You can fork the project on github for that.

As a side-note, I find it interesting that some people prefer writing blog posts about ugly work-arounds for weird problems over actually telling the developers about it. So, thanks for filing this ticket.
