 Hi all,
 
 The same bug has bitten me on my 5.3 system.
 
 This is apparently a known issue, per the netpbm-10.25 release notes
 @ http://sourceforge.net/project/shownotes.php?release_id=275719:
 
 "libpbm3.c won't compile if you use a -msse Gcc compile flag.
   The error is "undefined variable 'col'."  You need to add the
  declaration "int c;"."
 
 In fact, that doesn't appear to be totally correct; you need to simply
 declare "int col;"
 
 The port compiles successfully with the following patch, though I have
 not tested it yet:
