Hi,

I looked at the documentation of the <compiler> and <cc> tags. It does not  
look flexible enough to define your own compiler and it does not support  
clang yet.
So I see these options:
1- lobby with the lang/gcc port maintainer to (optionally) install without  
a ${SUFFIX} set on FreeBSD 10 (where gcc is gone).
2- change the build.xml to directly use the <exec> target.  
http://ant.apache.org/manual/Tasks/exec.html
3- symlink /usr/ports/graphics/jogl/work/gcc -> /usb/bin/cc and add the  
work directory to the PATH before building the port. This will actually  
build with clang. Which might or might not work.

I think option 2 is the most convenient and clear.
