Comment(by matt.cottrell@…):

 I'm ferreting out why arb does not build with clang.  It seems to be a
 problem with CPP.

 I configured clang as the compiler and set the following build arguments:

 {{{
                         configure.compiler clang

 build.args              GCC=${configure.cc} \
                         GPP=${configure.cxx} \
                         CPPreal=${configure.cpp}
 }}}

 But it appears that ${configure.cpp} is empty.

 {{{
 shell command " cd
 "/opt/local/var/macports/build/_Users_cottrell_Documents_Programming_MacPorts_ports_science_arb/arb/work/arbsrc_6779"
 && /usr/bin/make -j2 -w all GCC=/Developer/usr/bin/clang
 GPP=/Developer/usr/bin/clang++ CPPreal= " returned error 2
 }}}

 What can I do to satisfy the CPPreal needs of arb?
