ENV to macports

[Timothy Lee]

Is it possible to 'pass in' environment variables to the 'port  
install' command?

Or is the only way to pass something like CFLAGS to macports is  
through a portfile?

For example... I would like to
$sudo port install pan2 CFLAGS="-isysroot /Developers/SDKs/ 
MacOSX10.4u.sdk"

thoughts?
