 Priority:  Normal                   |  Milestone:
Component:  ports                    |    Version:  2.7.2
 Keywords:  powerpc, leopard, ppc64  |       Port:  luajit
-------------------------------------+--------------------
 When trying to build `luajit` on 10.5.8 default gcc-4.2 compiler is
 chosen, but it is not supported:

 {{{
 lj_arch.h:453:2: error: #error "Need at least GCC 4.3 or newer"
 }}}

 Specifying a newer compiler, build for ppc64 fails:


 {{{
 lj_arch.h:313:2: error: #error "No support for PPC64"
  #error "No support for PPC64"

 There is also a patch to be added for it to build for ppc:

 }}}

 After that it installs:

 {{{
 36-85:~ svacchanda$ port -v installed luajit
 The following ports are currently installed:
   luajit @2.1.0-beta3_5 (active) requested_variants='' platform='darwin 9'
 archs='ppc' date='2022-03-20T02:25:28+0800'
 }}}

 It also works for 10.6 PPC with the same corrections and patch.
