Iain,

Playing with the SCons tests, I am heading to the hypothesis that, at
least on Debian Sid, if both gdc and ldc packages are installed, then
gdc picks up the D source files from the ldc package in preference to
the ones from the gdc package.

I think this is the same problem I have on OS X.

Looks like a packaging issue. In Archlinux there is one extra directory
level for the compiler (e.g. `/usr/include/dlang/<compiler>/`) to prevent
such things.

Looking at the file list for both libraries:
- GDC: https://packages.debian.org/sid/amd64/libphobos-4.9-dev/filelist
- LDC: https://packages.debian.org/fr/sid/amd64/libphobos2-ldc-dev/filelist

It seems that indeed GDC is picking LDC's libphobos.
