segfault on linux with PE

Sorry to disturb, but I'm not clear how to proceed here.

Lispworks Personal Edition on my home gentoo install, crashes on start.  It's not clear to me why, though I see "GTK" mentioned, which I have installed.

Output below - have I missed something?  The backtrace and google are no help.
