# Our default setup excludes anything from /usr/ucblib (and consequently dbm)
# as later modules assume symbols found are available in shared libs
# On svr5 these are static archives which causes problems for
# dynamic modules loaded later (and ucblib is a bad dream anyway)
#
# However there is a dbm library built from the ucb sources outside ucblib
# at http://www.sco.com/skunkware (installing into /usr/local) so if we
# detect this we'll use it. You can change the default
# (to allow ucblib and its dbm or disallowing non ucb dbm) by
# changing 'want_*' config values below to '' to disable or otherwise to enable
# Leave leading tabs so Configure doesn't propagate variables to config.sh

If you wish to use dynamic linking, you must use
LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
or
setenv LD_LIBRARY_PATH `pwd`
before running make.
If you are using shared libraries from /usr/local/lib
for libdbm or libgdbm you may need to set
LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH
in order for Configure to compile the simple test program
