How to configure MacPort to pick already installed packages

I have recently shifted to OSX environment, so don't know much about MacPorts.

Is there a way to tell MacPorts to pick already installed packages. For instance to install

sudo port install meld

its requiring hell lot of packages, including python2.6. B开发者_C百科ut I already have python2.6 installed.

No there isnt. If you want to link against system installations then use Homebrew or compile manually yourself. Personally i prefer Macports because its completely isolated. Ive got plenty of disk so having duplicates doesnt bother me.
