mucade's ebuild hardcodes the D compiler to gdmd, which is a gcc implementation of a D complier. This was provided with the USE=d flag... in gcc-4.1.2 I attempted to re-build gcc-4.1.2 with d support, but this went south, dying with: (guess it hasn't been touched recently?) checking If /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/gdc -B/var/tmp/portage/sys-devel/gcc-4. 1.2/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_6 4-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include can compile D sources... /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/cc1d: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/libstdc++. so.6) no configure: error: can't compile D sources! so I made a chroot with an actual environment from back in 2009 (or so) when building gdc actually worked. I then created a binpackage from this, and re-tried to install mucade. this time it died with some missing symbols during linking: src/abagames/util/bulletml/bullet.o: In function

Always
"Fixed" by dropping package: 1) real maintainer is lost, 2) gentoo has no "gdc" (D compiler) in sys-devel/gcc. == 3) Game itself looks abandoned by author too ==
