As shown here (http://go-mono.com/sources/) mono, libgdiplus, xsp, mod_mono were updated.
xsp2 v. 1.1.10 contains serious bugs, however updating ebuild to 1.1.13 comes to changing the name of the ebuild (tested), so please update it in portage.
xsp is now at 1.1.15 mono is now at 1.1.15 libgdiplus is now at 1.1.15 mod_mono is now at 1.1.14 see http://www.go-mono.com/sources/
New versions of xsp and mod_mono are now in portage. Thanks!
