Did the gdc executable name change? I tried to build the 2.068.2 FE + gcc-4.9 tag on gcc-4.9.4 and it installed as "gdc" while all other compiler binaries installed in triplet format (e.g. x86_64-pc-linux-gnu-c++) with "c++" being a symlink. I remember it being that way for gdc, too. (I'm using Gentoo Linux's gcc ebuild (install script) patched with gdc, if that makes a difference.)
