Which combination of kernel/libc is failing ?

libc0.1 2.3-1+kbsd.14 + kfreebsd-image-5.4-1-686 5.4-8
libc0.1 2.3-1+kbsd.11 + kfreebsd-image-5.4-1-686 5.4-8
libc0.1 2.3-1+kbsd.11 + kfreebsd-image-5.4-1-686 5.4-7

Of course kernel have to be running, not only installed.

Please specify version also of version and package 
of mysql-server - 4.1 or 5.0 ?
