Hi Anirban,
Just a quick note to thank you again and inform you that you were quite right.
The build of gfortran that you recommended still has a broken link, but it is still available here:
http://cran.r-project.org/bin/macosx/tools/gfortran-4.2.3.dmg
Once this is installed alongside Xcode 4.6 and Xcode 5.0 DP, both inline and sourceCpp now work perfectly, and Xcode development appears to be unaffected.
Best regards
John
