I'm having trouble running gdl on OS X 10.8.4. I installed it using macports and it seemed to install fine, except it errors out anytime I try to run it.
$ sudo port install gnudatalanguage
Segmentation Fault: 11
I'm having the same issue. I ran a backtrace on gdl, and here's what I get:

bzip2 was installed as a dependency of gdl, and I verified that it exists:
$ which bzip2
Additionally I don't know why it would be looking for the bzip2 library files in the macports 'build' folder, those are long gone after the build completes (at least I think they are).
Actually, I should mention that like Randall W below, gdl was working for several months (maybe the last 5-6 months) and the current issues arose when I was forced to reinstall OS X and reinstall macports and gdl. Whatever the problem is, it only arose in the last few months. Because gdl hasn't changed versions in the last few months, it may be an issue with one of the dependencies.
Anyone have any thoughts or suggestions?
Same issue although I had originally installed mine about a month ago and it had been working fine until a couple of days ago. Now it segfaults on startup. A few things changed at that time: OSX installed an update and I also installed gnuradio, which pulled in a zillion dependencies. Any debugging advice appreciated- I'm considering the drastic step of a complete un/re install of macports since I use gdl all the time.
If you look at the edit I added to my previous post, you'll see that I had gdl working for quite some time and it wasn't until I had to do a complete reinstall, from scratch, that gdl stopped working. So I don't a complete un/re-install will help you much. Though if it does, let me know. Maybe it has to do with the order that I installed my various software.
