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

112 # In addition, on some systems there is a problem with perl and NDBM
113 # which causes AnyDBM and NDBM_File to lock up. This is evidenced
114 # in the tests as AnyDBM just freezing. Apparently, this only
115 # happens on a.out systems, so we disable NDBM for all a.out linux
116 # systems. If someone can suggest a more robust test
117 # that would be appreciated.

123 # I tried compiling with DBM support and sure enough things locked up
124 # just as advertised. Checking into it, I found that the lockup was
125 # during the call to dbm_open. Not *in* dbm_open -- but between the call
126 # to and the jump into.
128 # To make a long story short, making sure that the *.a and *.sa pairs of
129 # /usr/lib/lib{m,db,gdbm}.{a,sa}
130 # were perfectly in sync took care of it.
132 # This will generate a harmless Whoa There! message

153 *********************** Warning! *********************
154 It would appear you have a defective bash shell installed. This is likely to
155 give you a failure of op/exec test #5 during the test phase of the build,
156 Upgrading to a recent version (1.14.4 or later) should fix the problem.
