Hi, I use the root port for my work, and I was surprised this morning that
everything stopped working after I did a cleanup of all my "leaves" ports.
root is used as a C++ interpreter, but it also trivially can be used to compile
programs that use its libraries (usually by adding a + to a command string).
Apparently when it is used to compile stuff, the compiler that was used to
compile root is called.
My root was compiled with clang-3.2, but this is listed only as a build
dependency, not a lib dependency. I got reasonably informative error messages
("/opt/local/bin/clang++-mp-3.2: No such file or directory"), but I am
wondering if maybe the compiler should be listed as something other than a
build directory, given that compiling root macros and programs is a pretty
standard functionality of root. I.e. root without a proper compiler is
basically broken.
My solution was to add clang-3.2 as a requested port, but really I only use it
via root, so this feels un-MacPorts-like to me. Adding the compiler as a lib
dependency doesn't feel really appropriate either, since it's not being used as
a library, but rather is called externally. Perhaps experts can chime in about
how they feel?
