>Description:

Running a -current kernel and some slightly older userland causes core
dummps due to bad system calls:

  5233      1 python2.6 CALL  _ksem_init(1,0x7f7fffffd978)
  5233      1 python2.6 RET   _ksem_init -1 errno 78 Function not implemented
  5233      1 python2.6 PSIG  SIGSYS SIG_DFL: code=SI_NOINFO
  5233      1 python2.6 NAMI  "python2.6.core"

Just invoke the older python w/o arguments.
