The D installer should install the support files. specifically, at a minimum, it needs to install the /druntime/import and /phobos/src directories. see this thread for more info: http://forum.dlang.org/thread/nhckrtzepubypycrqcsi@forum.dlang.org thanks!
druntime and Phobos are installed in /usr/share/dmd/src as together with the rest of the compiler. If Mono-D can't find the necessary file you need to properly configure Mono-D or take it up with the the Mono-D developers. If the compiler should be installed somewhere else it's a different issue.
thanks! found it! i did a search before and finder didn't come up with anything, maybe it's because it's a hidden directory? anyhow, thanks!
