Thanks, Roland. Apparently /usr/ports/misc/compat5x is installed:
============================================
toutatis# make install clean
===>  Installing for compat5x-i386-5.4.0.8_11
===>   compat5x-i386-5.4.0.8_11 depends on file: 
/usr/local/share/compat/locale/UTF-8/LC_CTYPE - found
===>   Generating temporary packing list
===>  Checking if misc/compat5x already installed
===>   compat5x-i386-5.4.0.8_11 is already installed
=============================================

And...

ls -al /usr/local/lib/compat/libm.*
-r--r--r--  1 root  wheel  120004 Dec 13 06:18 /usr/local/lib/compat/libm.so.

I am using the stock 8.0-RELEASE kernel on a 3-week old install.

Any other ideas on where the conflict/problem may lie?
