 Priority:  Normal                |   Milestone:                                       
Component:  ports                 |     Version:  1.8.0                                
 Keywords:  fetch extract.suffix  |        Port:  unzip                                
----------------------------------+-----------------------------------------
 The extract.suffix for unzip, version 6.0, is incorrectly listed as
 .tgz
 in the portfile instead of
 .tar.gz

 With .tgz, fetch fails, with .tar.gz, fetch succeeds and the port
 successfully builds with variant +universal on 10.6.1 on an Macbook 2.1.

 http://sourceforge.net/projects/infozip/files/
 lists a source file unzip60.tar.gz with .tar.gz as suffix.
