let me know if you need more info. gdb also fails: sudo port install gdb

Error: Target org.macports.build returned: shell command failed (see log for details)

Please use WikiFormatting.

Please re-read the error message you pasted above. It tells you how to use xcode-select to fix the problem.

Doesn't work, I run two commands 1. sudo xcode-select -switch /Applications/Xcode.app and 2. sudo port install zlib. It gives the same error/warning. Let me know how to proceed. Thanks for the help.

What happens when you run /usr/bin/xcodebuild -version ?

[rajeeja@…]

Thanks it works now.
