[svn-r4422] Purpose:
    Portability Bug Fixes
Description:
    FreeBSD wants the -pthread flag on both the compile and link lines.  Also,
    the cipher library is required for certain threading features and needs to
    be linked in.
Solution:
    Add the -pthread to the compile line and the cipher library to the list of
    libraries.
Platforms tested:
    FreeBSD 4.4 (hawkwind)
