 Revision 53399 makes a change to how configure is invoked, altering CPATH
 and LIBRARY_PATH over passing -L to configure.

 Downstream, this causes py26-pyqt4 to fail to build as it is unable to
 find -lpng, as there is no -L${prefix} in the Makefiles generated by
 qmake.

 Perhaps this is the case in any project depending on qt4-mac.
 Unfortunately qmake is a bit of a mystery to me.

 If the Portfile is patched to include -L in the configure args then
 py26-pyqt4 builds correctly.

 I suspect that all of the -isystem and -L flags need to be returned as
 opposed to manipulating CPATH and LIBRARY_PATH.

 Patch attached only adds the -L flag to allow py26-qt4 to build.  Probably
 the other variants need to add -L's over using LIBRARY_PATH as well??
