I saw errors like that when compiling mod_php4, which was due to it trying to 
link in the libssl and/or libcrypto libraries.  You can probably see the 
exact error by looking in the config.log file.  These libraries are in the 
base system and will be installed in /usr/local if you install openssl from 
ports.  There are a couple of possible solutions:

1. Find the patch for /usr/ports/Mk/bsd.port.mk which forces it to use 
OPENSSLBASE/USE_OPENSSL_PORT directives in your make.conf file.  I have it, 
and it's been posted to this list in the past few weeks.

2. You could also try temporarily symlinking /usr/lib/libssl.so/libcrypto.so 
to the newer versions in /usr/local and see if that fixes it.

I've done both and things seem to be able to compile and work properly.  There 
are only a few things in the base system that link against them (sshd, pppd, 
etc).  I decided to use the ports ssh rather than the base, so this hasn't 
been a big inconvenience to work around the openssl library issue.

HTH.
