#57191: leptonica @1.76.0 requires giflib 5
------------------------+-----------------------

     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:
 Keywords:              |       Port:  leptonica
------------------------+-----------------------
 leptonica has a dependency on giflib but as of version 1.76.0 it does not
 use it because it now requires giflib 5 while MacPorts still has giflib 4:

 {{{
 checking for DGifOpenFileHandle in -lgif... yes
 checking gif_lib.h usability... yes
 checking gif_lib.h presence... yes
 checking for gif_lib.h... yes
 checking giflib is at least version 5.1 (but not 5.1.2)... no
 }}}

 Our options are:

 1. Remove the giflib dependency from leptonica, add a configure arg to
 tell it not to try to use giflib, and increase leptonica's revision
 2. [ticket:49876 Upgrade giflib to version 5], and increase leptonica's
 revision to rebuild it
