The "obvious" solution is to have a gdmd.conf file which specifies what gdc
executable to use and where to find it. This should get round problems such as
gdc being installed in /opt/gdc/bin and gdmd being in /usr/local/bin.
The default would be to select the gdc used to actually build gdmd, with an
option to configure for alternative locations.
findGDC() should probably prioritize in this order:
* If there's a gdmd.conf, use the gdcDir specified. There probably
needs to be a search priority of where to find the .conf file.
* If not, use which gdc to identify what gdc to call
(and possibly display a warning that there's no gdmd.conf?)
On a related note, can you clarify what the issues are with findScriptPath ... ?
