Quick and unportable (Linux-only) drop-in replacement:

string findGDC(string argv0)
{
     // FIXME: this does not work 100% of the time.
     auto c = match(baseName(argv0), 
`^(.*-)?g?dmd(-.*)?$`).captures;
     auto targetPrefix = c[1];
	
	auto which = executeShell("which gdc");
	if (which.status == 0){
		writeln("Failed to execute which.");
	}
	else {
		writefln("which returned %s", which.output);
	}
	
	auto gdcDir = absolutePath(dirName(which.output));
	writefln("new findGDC: gdcDir=%s", gdcDir);
     return buildNormalizedPath(gdcDir, targetPrefix ~ "gdc" ~ 
c[2]);
}
