It says:

  is only  granted upon approval from Yousef  Saad.  Not  any portion of
  SPARSKIT can   be used  for  commercial  purposes  or  as  part of   a
  commercial package.  This notice should accompany   the package in any
  approved copy.

  Note to contributors: Before  contributing any software be aware  that

which as I see it is incompatible with the GPL.  The GPL doesn't place
any restriction on commercial use.
