+You don't have an ELF gcc. I will use dld if possible. If you are
+using a version of DLD earlier than 3.2.6, or don't have it at all, you
+should probably upgrade. If you are forced to use 3.2.4, you should
+uncomment a couple of lines in hints/linux.sh and restart Configure so
+that shared libraries will be disallowed.

+ # just as advertised. Checking into it, I found that the lockup was
+ # during the call to dbm_open. Not *in* dbm_open -- but between the call
+ # to and the jump into.
