With SL upgrade, as discussed before there is problem with LaTex and other bundles don't work while the tm_interactive_input.dylib exists.

I find another problem when I tried to configure the LaTeX bundle preference, it appears a tooltip says,

/Library/Applications Support/TexMate/Bundles/LateX.tmbudle/Support/ bin/configure.py:8: DeprecationWaring: os.popen4 is deprecated. Use the subprocess module. sin,result = os.popen4(command)

What is this?
