MacPorts & ROS

edit

I tried to install ROS on a fresh OS X with Homebrew (https://github.com/mxcl/homebrew/), but it didn't worked correctly... So i switched back to MacPorts. After installing different ports, i tried to build ROS. It did not work. I had to add -I/opt/local/include to CMAKE_CXX_FLAGS and now it would compile but there are linker failures?¿?

ld: warning: ignoring file /opt/local/lib/libboost_signals-mt.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

When i run make with VERBOSE=1, this are the last line of output

Why want cmake link with flag -arch i386? Is there a reason for this?

(The port boost was not compiled as universal.)
