Comment(by cal@…):

 Please remember to Cc or assign to the maintainer.

 mod_passenger uses /usr/bin/rake in it's configure phase; does it also
 link against (or use at run-time) system ruby? Per MacPorts
 wiki:FAQ#ownlibs we do not link against or use system libraries, but
 should rather depend on one of the ruby port available in MacPorts to be
 self-contained. This patch should probably add a dependency on MacPorts
 ruby and set environment variables or patch Makefiles/configure where
 necessary to make it use MacPorts ruby.

 mod_passenger also seems to ship it's own version of libev:
 {{{
 cd ext/libev/ && sh
 /opt/local/var/macports/build/_opt_dports_www_nginx/nginx/work/passenger-3.0.11/ext/libev/configure
 --disable-shared --enable-static
 }}}
 Is this necessary? Can MacPorts' libev port be used instead? What are the
 reasons for mod_passenger shipping it's own libev?

 Also actually compiling mod_passenger seems to ignore the CC environment
 variable specified at configure time and always use "gcc" instead. We
 usually always specify an explicit compiler and want software to use this
 compiler in order to get reproducible builds. Maybe this patch needs to
 add
 {{{
 build.args-append       CC=${configure.cc} \
                         CXX=${configure.cxx} \
                         CPP=${configure.cpp}
 }}}
 as described in UsingTheRightCompiler?

 The error output I see is:

 The last paragraph in using UsingTheRightCompiler describes the test setup
 I have on my development system in order to test for ports using the
 default compiler (and is what is causing the error message I pasted). You
 will not see this without this special setup.
