If you have already installed pfstools on your computer, the most
probable reason is a badly set environmental variable PKG_CONFIG_PATH.
You have to make sure that the file pfs.pc is in one of directories
listed in this variable or in /usr/lib/pkgconfig. You may need to add
an additional directory (in bash):

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

If this does not help, please send your config.log file.
