I just tried. I'm on CentOS 6.3, and get
semanage fcontext -a -t passenger_exec_t
"/opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.15/bin/*"
libsepol.context_from_record: type passenger_exec_t is not defined (No
such file or directory).
libsepol.context_from_record: could not create context structure (Invalid
argument).
libsemanage.validate_handler: invalid context
system_u:object_r:passenger_exec_t:s0 specified for
/opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.15/bin/* [all files]
(Invalid argument).
libsemanage.dbase_llist_iterate: could not iterate over records (Invalid
argument).
/usr/sbin/semanage: Could not commit semanage transaction
