The attached patch applied over current ebuild adds an or-dependency on glibc or libiconv for glib2. This is needed for non-glibc systems which needs libiconv to build glib2 (libiconv is hardmasked at the moment, but they should be able to unmask it where needed). The change is a no-op for glibc users. HTH, Diego

Changing this in a more descriptive bug report for G/FBSD. CCing herds for packages involved.
Grep, too.
Ok as there's a bit of a problem (gcc automatically links against libiconv if it founds it), I'm adding this to profile (also if I'd rather avoided that).
