Since there's no amd64 ebuild for this game, I tried to unmask it with x86 keyword. It refuses to compile, and here's what I got when trying to emerge it. After these error messages, here's my emerge --info too. I don't know if it's a bug, and amd64 incompatibility or anything else... but what I'm sure is that a really would like to play this game on my computer :) # emerge warzone2100 (...) /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/X11R6/lib/libphysfs.so when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/X11R6/lib/libphysfs.a when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../libphysfs.so when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../libphysfs.a when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/lib/libphysfs.so when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: skipping incompatible /usr/lib/libphysfs.a when searching for -lphysfs /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lphysfs collect2: ld returned 1 exit status make[3]: *** [warzone2100] Error 1 make[3]: Leaving directory `/var/tmp/portage/warzone2100-2.0.4/work/warzone2100-2.0.4/src' make[2]: *** [all] Error 2 make[2]: Leaving directory `/var/tmp/portage/warzone2100-2.0.4/work/warzone2100-2.0.4/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/warzone2100-2.0.4/work/warzone2100-2.0.4' make: *** [all] Error 2 !!!
