Comment (by mojca@…):

 I'm totally confused. I don't see the {{{-arch x86_64}}} flag in FFLAGS or
 FCFLAGS indeed. And yet, when I compile the sources outside of MacPorts
 with the same compiler I end up with
 {{{
 Fortran_FLAGS =  -m64 -std=legacy -fPIC -I<some includes>
 }}}
 and inside MacPorts I end up with
 {{{
 Fortran_FLAGS =  -m64 -std=legacy -O3 -arch x86_64 -fPIC -I<some includes>
 }}}
 in {{{build/misc/minicern/CMakeFiles/minicern.dir/flags.make}}} for
 example.

 However:
 {{{
 DEBUG: Environment: CPATH='/opt/local/include' CFLAGS='-pipe -O2 -arch
 x86_64' CPPFLAGS='-I/opt/local/include' CXXFLAGS='-pipe -O2 -arch x86_64'
 LIBRARY_PATH='/opt/local/lib' MACOSX_DEPLOYMENT_TARGET='10.7'
 CXX='/usr/bin/clang++'
 CC_PRINT_OPTIONS_FILE='/Users/mojca/.macports/opt/local/var/macports/build
 /_Users_mojca_app_macports_localports_science_root-devel/root-
 devel/work/.CC_PRINT_OPTIONS' F90FLAGS='-pipe -O2 -m64'
 LDFLAGS='-L/opt/local/lib -arch x86_64' FCFLAGS='-pipe -O2 -m64'
 OBJC='/usr/bin/clang' INSTALL='/usr/bin/install -c' FC='/opt/local/bin
 /gfortran-mp-4.5' OBJCFLAGS='-pipe -O2 -arch x86_64' FFLAGS='-pipe -O2
 -m64' CC_PRINT_OPTIONS='YES' CC='/usr/bin/clang'
 }}}

 I'm using the same cmake and same compilers to compile both inside and
 outside of MacPorts. Any clues?
