Actually, I have a p7zip i-Package in the *Experimental* i-Directory  
both for i386 and powerpc. But I did compile the unix port of P7ZIP,  
which is p7zip_4.14.01 and which can be found on SourceForge.

I run something like

         (cd "${P7ZIPSOURCES}" && make clean )
         (cd "${P7ZIPSOURCES}" && cp makefile.macosx makefile.machine )
         (cd "${P7ZIPSOURCES}" && make all2 )
