There are new versions of libhx available at <http://jengelh.medozas.de/files/libHX/libHX-1.23.tar.bz2> and <http://jengelh.medozas.de/files/libHX/libHX-1.25.tar.bz2>. libhx 1.23 is necessary for pam_mount 0.47 libhx 1.25 is the newest one so I believe it should be available too. I have libhx 1.23 working with pam_mount. I've just renamed libhx-1.18.ebuild to libhx-1.23.ebuild and it seems to be fine.
Seems that latest pam_mount doesn't like 1.25, so I'll stick with 1.23 for now. Will leave this bug open, but as pam_mount seems to be the only package using libhx, it probably doesn't make sense to provide any 1.25 package yet.
