+       library or the <command>libgpfs</command> library is needed at
+       runtime by the <command>gpfs</command> VFS module:
+       Starting with gpfs 3.2.1 PTF8, the complete <command>libgpfs</command>
+       is available as open source and <command>libgpfs_gpl</command> does no
+       longer exist. With earlier versions of gpfs, only the
+       <command>libgpfs_gpl</command> library was open source and could be
+       used at run time.

+       <para>
+       At build time, only the header file <command>gpfs_gpl.h</command>
+       is required , which is a symlink to <command>gpfs.h</command> in
+       gpfs versions newer than 3.2.1 PTF8.
