Ahh, sweet. Didn't know about that "Status:" thing. Or maybe I did and 
forgot... ;)

BTW, another thing I just learned (posting here in case anyone reads this 
and has similar problems) is that on some servers, like mine, the 
permissions on the executable have to be set to *not* be writable by group 
or world, or Apache will just throw a 500. Apperently there's a whole list 
of conditions that have to be met here:
http://httpd.apache.org/docs/current/suexec.html

When I first compiled the app on my local CentOS VM, gcc set the binary's 
permissions to 775, which were preserved by ftp, and then I could run it on 
the server through ssh, but not through Apache/HTTP. Changing them to 755 
fixed it.

Yea, that would definitely a better way to go. Unfortunately I normally have 
to deal with shared hosts, so the stuff I can actually do on the server is 
usually very limited. On this particular server, I know I can't run gcc. (At 
least not the system's gcc anyway. Maybe there's some way to have a portable 
install of gcc? But knowing gcc, if there is a way, I'm sure it would be a 
royal pain.) DMD *is* a portable install, which is nice, but on linux it 
still needs gcc to link. And then on the other server I need to use, I don't 
think ssh is even available.
