how is it one runs non-static freebsd binaries?

first it can't find the information:
./irc-2.8.2
/usr/libexec/ld.so: irc-2.8.2: libtermcap.so.2.1: No such file or directory

then once I've added it with ldconfig, it complains:
./irc-2.8.2
/usr/libexec/ld.so: irc-2.8.2: libtermcap.so.2.1: Inappropriate file type or format

whats up?  can I put these into /emul/FreeBSD and have it work better?
Give me a hand with this and I'll write a starting COMPAT_FREEBSD man page.
