33 | # Our default setup excludes anything from /usr/ucblib (and consequently dbm) |
34 | # as later modules assume symbols found are available in shared libs |
35 | # On svr5 these are static archives which causes problems for |
36 | # dynamic modules loaded later (and ucblib is a bad dream anyway) |
37 | # |
38 | # However there is a dbm library built from the ucb sources outside ucblib |
39 | # at http://www.sco.com/skunkware (installing into /usr/local) so if we |
40 | # detect this we'll use it. You can change the default |
41 | # (to allow ucblib and its dbm or disallowing non ucb dbm) by |
42 | # changing 'want_*' config values below to '' to disable or otherwise to enable |
