 Hi. I just tried an installation of VTK (the default, 4.4.2), which
 failed, apparently with the following error:

 {{{
 :info:build c++: unrecognized option '-no-cpp-precomp'
 }}}

 I'm on a Macbook Pro running 10.6.8, with an up-to-date MacPorts
 installation, and gcc 4.5.3 as my default compiler collection.

 I'm attaching the install log.

Comment:

 MacPorts does not use your default compiler collection. On Snow Leopard
 with Xcode 3.x it will use gcc-4.2; with Xcode 4.0 or 4.1 it will use
 llvm-gcc-4.2; and with Xcode 4.2 it will use clang. What version of Xcode
 do you have?

 At least, that is what's supposed to happen, but we see in the log it's
 actually using /opt/local/bin/gcc. That's a bug in the port; the port
 needs to ensure it's UsingTheRightCompiler.
