BixServer Path Issue on FreeBSD 4.7

When starting BixServer-2.5-freebsd-1-DB version of runserver.sh I get:

./runserver.sh
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap
ELF interpreter /libexec/ld-elf.so.1 not found

Abort trap
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap

Notice that it's looking for /libexec where on our server libexec is in /usr/libexec... Is that path hard-coded in bixserver?
