I reported this a couple of weeks ago but it must have got lost when the mail list was eating everything sent to it.
Heres the latest hints file for UnixWare7. Its expanded on the previous update with suppression of use of libucb (which causes problems with some later loaded modules)\, use of skunkware available ucb libdbm from /usr/local and additional lib linkage for early uw7 versions execution ability (doc of preferred fix) and various other tweaks..

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
