There is an issue where the python package managers by default install the 32 bit versions of packages. If you are running 64 bit architecture this is a problem. In this instance you need ensure that 64 bit version of MySQL Python is installed and being used, if not you may see an error message like the following: {{{ ERROR: ImportError: ("couldn't load store for tiddlywebplugins.tiddlyspace.store: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_mysql.so, 2): no suitable image found.
Did find:\n\t/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_mysql.so: mach-o, but wrong architecture, No module named tiddlywebplugins.tiddlyspace.store",) }}}

To resolve this you need to export the following environment variable before installing the package (you may have to remove the package and reinstall)

!!!!! Exports (add to .bash_profile): {{{ export ARCHFLAGS='-arch ppc -arch ppc64 -arch i386 -arch x86_64' #So pip will install 65 bit }}} You also need to export a variable identifying where the MySQL installation is: {{{ export DYLD_LIBRARY_PATH=/usr/local/mysql/lib }}}
