YEE HAW! The problem is fixed!
The machine:
FreeBSD 3.4-STABLE
(ctm 451)
The Problem:

The Solution:
Alfred Perlstein wrote: <snip> the symlinks are set properly for you to use
the 3 version of the library (you may want to copy libc_r.so.4 over
libc_r.so.3).
So,
chflags noschg libc_r.so.3
mv libc_r.so.3 libc_r.so.3.bkp
cp libc_r.so.4 libc_r.so.3
Voila'!
Why does this work?
Apparently (remember I'm not a C programmer) CGPro is being linked against
libc_r.so.3 (which on FreeBSD appears to be an older library) as evidenced by:
archives# ldd CGServer
CGServer:
libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x281c8000)
libc_r.so.3 => /usr/lib/libc_r.so.3 (0x281dd000)
instead of libc_r.so which symlinks to the latest library - libc_r.so.4. Now
something else must also be going on while making world or compiling the
kernel, because it seems to me that if the library libc_r.so.3 is physically
there it should also be available for use, but apparently not.
I'll keep copies of the email I've sent back and forth if anyone wants them,
otherwise, just count me as one very happy camper!
Thanks to everyone who had suggestions, everyone of them was valuable and
helped point me in the right direction!
