This is just bad:

main(string[] args) calls init(args) that calls findGDC(args[0]) 
that gives auto gdcDir = absolutePath(dirName(argv0));

Which is not good:

findGDC: argv0=gdmd
findGDC: dirName(argv0)=.
findGDC: gdcDir=/home/user/github/gdmd/.

That is: it will look for gdc in the current folder, which is not 
even the base folder of gdmd (eg. /usr/bin), but the working 
directory.

In other words, it looks for gdc in the current working folder.

Then it complains:

Not an executable file: /home/user/github/gdmd/gdc

which is understandable.

I think it should simply look on the PATH.
