You are quite right. Useful info is found in config.log. The configure script try to compile a nd link a conftest.c which refers gdbm_open(), but is not find in libgdbm. The problem in my case is that gdbm installation only creates libgdbm.so.2.0.0 in /usr/local/lib, where the compile command uses -lgdbm. After I made symbolic link to libgdbm.so, works.
However, using db2 has slightly different problem. The configure script finds the right now trys to link to -ldb, and get error for "db_open... no".
command "nm libdb.a |grep db_open" list only __db_open but not db_open. This will surely cause failure.
Is this a bug in configure or due to changes in db2 ? I use BerkeleyDB3.1.17 downlowded from Sleepycat.

config.log should provide details as to why detection is failing.
Likely due to poorly set environment variables...
