However, I guess there still will be a problem with regression tests, 
because pg_crypto will reports error in case when user tries to use 
stronger cipher, but it generates diff between expected and real output.

I don't know if is possible select different output based on test if 
strong crypto is installed or not. Maybe some magic in 
Makefile/Configure. Test should be:

# ldd /usr/postgres/8.2/lib/pgcrypto.so  | grep libcrypto_extra
#   libcrypto_extra.so.0.9.8 =>      (file not found)

if output contains (file not found) library is not installed or not in 
path (/usr/sfw/lib).
