------------------------+--------------------------------
 While upgrading p7zip from 9.38.1_1 to 15.09_0 on 10.5.8 I found that a
 compiler is being selected which is not available

 {{{
 ...
 :debug:configure Using compiler 'Xcode GCC 4.2'
 ...
 :info:build /usr/bin/llvm-gcc -c -I. -I../../../../C -I../../../myWindows
 -I../.
 ./../include_windows -I../../.. -m64 -O -DENV_MACOSX
 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_REENTRANT -DENV_UNIX -arch
 ppc  -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_REENTRANT -DENV_UNIX
 -DBREAK_HANDLER -DUNICODE -D_UNICODE -DUNIX_USE_WIN_FILE
 ../../../../C/7zCrc.c
 :info:build make[1]: /usr/bin/llvm-gcc: Command not found
 ...
 }}}
 ay
 I think this happens since llvm-gcc is the fallback compiler, and other
 Xcode compilers available are all blacklisted.

 What is strange is this: If I try to specify another compiler, say, gcc5,
 though it than tells me
 {{{
 ...
 DEBUG: Using compiler 'MacPorts GCC 5'
 ...
 }}}
 it still runs into
 {{{
 ...
 make[1]: /usr/bin/llvm-gcc: Command not found
 ...
 }}}
 So something seems to be mistakenly 'hardwired'. I will later on install
 MacPorts' llvm-gcc-42 and try if this helps.
