#55831: postgis2 fails to compile on Snow Leopard

     Type:  defect                |     Status:  new
 Priority:  Normal                |  Milestone:
Component:  ports                 |    Version:  2.4.2
 Keywords:  postgis2 SnowLeopard  |       Port:  postgis2
----------------------------------+----------------------
 I had to apply a modification to postgis2 Portfile in order for it to
 compile under Snow Leopard. I attach here the modified Portfile, where I
 added this code

 {{{
 build.args-append       CC=${configure.cc} \
                         CXX=${configure.cxx} \
                         CPP=${configure.cpp}
 }}}

  after

 {{{
 build.args                  ICONV_LDFLAGS='-L${prefix}/lib -liconv'
 }}}

 I'm not sure this is the correct solution, or if it breaks on newer
 systems, but it solved my issue...
