	I was unable to compile it (ArchLinux 64 bits). Apparently it fails
when building Phobos:

	I tried going to the x86_64-unknown-linux-gnu/libphobos folder and
typing the failing gcc command manually, it fails too. Then I tried
going to that folder and compiling a simple hello world and I got
the same result (the hello world compiles fine in another folder).
Finally, I ran the command under strace and here is the relevant
part of the trace:

	It appears that gcc looks for cc1 in the wrong location. It should
either take the system one
(/usr/lib/gcc/x86_64-unknown-linux-gnu/4.5.1/cc1) or one of those it
compiled itself (gcc/cc1  prev-gcc/cc1  stage1-gcc/cc1).

	The build was configured with:
> ../gcc-4.5.1/configure --prefix=/usr \
>     --enable-languages=d --enable-threads  --enable-__cxa_atexit \
>     --disable-multilib --libdir=/usr/lib --libexecdir=/usr/lib \
>     --disable-shared
> make

	I also tried adding C (--enable-languages=c,d) to no avail.
