When using the --with-<something> options in the configure you must do
--with-ppl=/usr/local/ for example. But the best way i have found is
by not building gcc within it source directory. So do somthing like:
$ mkdir gcc-build
$ cd gcc-build
$ ../gcc/configure --enable-languages=c,c++ --prefix=...
--with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib
--with-mpfr-include=/usr/local/include --with-mpfr-lib=/usr/local/lib
--with-ppl-include=.....
Would be a way i do it on my laptop where i have local installed
versions of the different depandancies. But i think using the
--with-ppl=/usr/local would work you just point it to the directory
were the respected lib and include folders are i think.
Hope this helps!
