The FHS suggests /opt/epics/<package> as the best location (although I admit 
that epics is not currently a LANANA registered provider name).  See
http://www.pathname.com/fhs/pub/fhs-2.3.html#OPTADDONAPPLICATIONSOFTWAREPACKAGES
for what it says about /opt.  That is where I usually install the code for 
training courses.

The FHS document also says:
    Large software packages must not use a direct subdirectory under the
    /usr hierarchy.
About /usr/lib it says:
    /usr/lib includes object files, libraries, and internal binaries that
    are not intended to be executed directly by users or shell scripts.
this /usr/lib/epics would not be appropriate for many things.
