As far as I know, the only dependency is a working C/C++ compiler.

$ ldd dmd/src/dmd
	linux-vdso.so.1 (0x00007ffff27ff000)
	libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fb068676000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb068459000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fb068155000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fb067f3f000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb067b95000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fb0689a1000)
$


So, nothing beyond your basic C/C++ system libraries.

Oh that's good to know. Maybe I should try building GDC 4.9 sometime...
