Trouble compiling gtkD under linux with gdc

[Graham St Jack]

The buildAll.sh script wouldn't work for me under Linux using gdc (gcc
4.1.2). I used the gtkD-pre2.zip archive.

The problems were:

* The scripts weren't executable.
* compd wasn't executable.
* The scripts assumed that "." is on the search path
* It only tried to use dmd (ie didn't try gdc as a fallback)

Is there a fix coming along soon?
