The dansguardian-2.9.6.1_alpha1 ebuild depends on dev-libs/libpcre. However, the package's configure script explicitly checks for and fails without libpcre-6.0 or greater. Please bump the libpcre depdenency version: pcre? ( >=dev-libs/libpcre-6.0 ) Thanks, Sheldon.
libpcre-6.3 is stable everywhere, use portage properly and upgrade with --deep, you won't have such problems then.
fixed in cvs. thanks for the tip!
