Well, evidently the configure script was trying to see if you had the
PQunescapeBytea function, and couldn't compile/run the script that tests
for that.

If you look in the log file that configure generates, you may discover
some reason why that failed to compile/run.

See config.log, and look near the end, as that's where the failure will be.

When it works, the log file will contain something like this:

configure:5948: checking for PQunescapeBytea in -lpq
configure:5979: gcc -o conftest -g -O2   -L/opt/OXRS/dbs/pgsql81/lib/
conftest.c -lpq   >&5
configure:5982: $? = 0
configure:5985: test -s conftest
configure:5988: $? = 0
configure:6000: result: yes

If it doesn't, you'll probably see some compiler errors.  Perhaps you
missed an include/library directory when running configure.
