p7zip @15.09 does not build on 10.5.8

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.

sudo port install llvm-gcc42
Error: llvm-gcc42 cannot be installed for the configured build_arch 'ppc' because it only supports the arch(s) 'i386 x86_64'.
