#43950: openjpeg build fails on 10.4 with missing symbols

 Keywords:          |       Port:  openjpeg
--------------------+--------------------------------
 Upgrading openjeg (2.0.0_1 < 2.1.0_0) fails on my 10.4.11 PPC system.  On
 10.4, the port depends on the `apple-gcc42` compiler port.  After a quick
 look, I'm not sure what is going on but one thing looks rather odd: it
 appears that `ld` may be incorrectly looking for MacPorts-installed
 library using the SDK root prefix (note, this installation uses a --prefix
 of `/macports` rather than `/opt/local`).  I wonder whether the addition
 of `-isystem` in r115051 is causing problems.
 {{{

 }}}

 For example, those first two symbols do appear to exist in the MacPorts-
 installed libjpeg:

 {{{
 $ nm /macports/lib/libjpeg.9.dylib | grep Create
 000011ac T _jpeg_CreateCompress
 0000d2e8 T _jpeg_CreateDecompress
 }}}
