I can confirm that the program is buggy, but I don't get exactly the same problems you do. I do show two processes running for it though, so I expect that that's its normal operation.
I personally can run and play it just fine, but it hangs when I try to shut it down with an error
"*** glibc detected *** double free or corruption (fasttop): 0x0815f998 ***".
The sound does stop on mine, however.
As for your link, that problem seems to be rather different. It was a linking problem that he solved by rebuilding and reinstalling the libtool libary (ports is the BSD system of program management). You could try installing/reinstalling libtool yourself, there must be an rpm for it somewhere, but I'm not sure it will help you much. On Debian gweled doesn't even list libtool as a dependency. OTOH, I tried installing it anyway and gweled now runs much faster than it did before. Go figure. Didn't solve the problems though.
This seems to be the homepage for it. The notes on the page don't give me much confidence for a quick resolution, but I might try building the newest release from source and see what happens.
And by the way, thank you for letting me know that this program exists. I always enjoyed playing bejeweled under windows, and still play it sometimes running under wine, but it's nice to know that there's a native port available. I do wish that there was some way to turn off the sound, though.
