[PyQt] Compiling PyQt4 with $ORIGIN

[Chris Hills]

In $QTDIR/mkspecs/common/g++.conf I have the following line:-

QMAKE_RPATH = -Wl,-enable-new-dtags 
-Wl,-rpath,\\\$$$$ORIGIN:\\\$$$$ORIGIN/../lib:/usr/local/Trolltech/Qt-4.5.2/lib 
-Wl,-rpath,

This works fine when compiling regular C++ applications, and results in 
binaries/libraries that have "$ORIGIN:$ORIGIN/../lib:[..]" in the RPATH 
and RUNPATH entries. However, when compiling PyQt4, it seems to get 
mangled and thus does not get applied properly. After running `python 
configure.py && make` the following excerpt can be observed (and happens 
for every library that is linked):-

g++ -shared -Wl,-O1 "-Wl,-enable-new-dtags -Wl,-rpath,\\\ 
-Wl,-rpath,/usr/local/Trolltech/Qt-4.5.2/lib" 
-Wl,--version-script=QtSql.exp -o QtSql.so sipQtSqlcmodule.o
