Some context. ReportLab windows exe installers for pythons 2.x x=4-7 are built on a single 32bit machine with 32bit pythons using a code that looks like this

set FT_LIB=c:\devel\libs_x86\freetype.lib
\python2x\python setup.py bdist_wininst --bitmap=%BMP% --title="ReportLab"

we build the 64 bit versions for 2.6 & 2.7 only. In those cases an extra step does

set FT_LIB=c:\devel\libs_amd64\freetype.lib
\python2.x\python setup.py bdist_wininst --bitmap=%BMP% --plat-name=win-amd64 --title="ReportLab"

To make this work I have copied from 64bit win32 installs of python2.6/7 various lib/dll/pyds. These live in 

C:\Python2x\PCBuild\AMD64

eg
C:\ux\ExeBuilder>ls \Python26\PCBuild\AMD64

_bsddb.pyd            _socket.pyd           pyexpat.pyd

_msi.lib              bz2.lib               unicodedata.lib
_msi.pyd              bz2.pyd               unicodedata.pyd
_multiprocessing.lib  py.ico                winsound.lib
_multiprocessing.pyd  pyc.ico               winsound.pyd

I followed most of section 5.4 in http://docs.python.org/distutils/builtdist.html to get this almost working, but got problems related to the library paths which my patch appears to fix (I seem to get working exes out of this approach).
