Try command:
$ fpc -iV
If you have properly installed FPC, it should prompt
2.6.4
Go to directory where you downloaded FPC.
Write:
$ svn update
$ make distclean
$ make all
$ su
***password***
make install
If everything went w/o errors, go to
/usr/local/bin
and change the symlink ppcx64 to path:
/usr/local/lib/fpc/2.7.1/ppcx64
Now try again:
$ fpc -iV
It should prompt
