I'd need to see the exact error message to be sure, but I'll hazard a guess:
You are using the latest Apple operating system and compiler with a (relatively speaking) older version of MATLAB. R2009b relies on GCC 4.0, which was included in similar-vintage versions of Xcode, but is no longer included in modern releases of Xcode. Here is what was supported at the time of 9b's release:
You'll probably have better luck with Xcode versions 3.1 or 3.2, if you can still find them and they are installable on Lion (on this I am unsure).

Yes, this version of MATLAB is looking for GCC 4.0, which is no longer included in Xcode, sorry.
