[Clfs-support] ppl and cloog-ppl errors amd64

[bv]

Greetings,

I am attempting to build  clfs current development   (amd64 64-bit).  I am at 
the  toolchain section and reached   the building of ppl-0.10.2.

The libraries built and installed then it reported  an error  for a binary.  
Being unsure if a binary was needed I  proceeded   with cloog-ppl-0.15.10  
only to run into more errors,  The error trails are shown below:-





 ppl-0.10.2  installation

test -z "/cross-tools/bin" || /bin/mkdir -p "/cross-tools/bin"
/bin/mkdir: cannot create directory `/cross-tools/bin': File exists
make[3]: *** [install-binPROGRAMS] Error 1
make[3]: Leaving directory `/mnt/clfs/sources-28810/ppl-0.10.2/src'
make[2]: *** [install-am] Error 2

make[1]: *** [install] Error 2

 cloog-ppl-0.15.10  compilation

It appears that your system is OK to start CLooG compilation. You need
now to type "make". After compilation, you should check CLooG by typing
"make check". If no problem occur, you can type "make uninstall" if
you are upgrading an old version. Lastly type "make install" to install
CLooG on your system (log as root if necessary).
