This is a packaging bug - since gnutls depends on gcrypt, the
gnutls-devel package should have Requires: libgcrypt-devel.

Well libvirt is not using libgcrypt - we're using gnutls. If gnutls 
happens to use libgcrypt internally then it should require it. We 
shouldn't have to second guess what dependant libraries gnutls is
requiring
