 While trying to update autotrace @0.31.1, Revision 5 this error occurs:

 {{{
 input-png.c: In function 'handle_warning':
 input-png.c:45: error: dereferencing pointer to incomplete type
 input-png.c: In function 'handle_error':
 input-png.c:53: error: dereferencing pointer to incomplete type
 input-png.c: In function 'read_png':
 input-png.c:160: error: dereferencing pointer to incomplete type
 input-png.c:161: error: dereferencing pointer to incomplete type

 input-png.c:196: error: dereferencing pointer to incomplete type
 input-png.c:197: error: dereferencing pointer to incomplete type
 }}}

 This certainly means that the installed version of

 {{{
   libpng @1.5.12_0 (active)
 }}}

 is not correct. It should be libpng14. At least the working
 /opt/local/bin/autotrace from autotrace @0.31.1_4 (active) has listed:

 {{{
         /opt/local/lib/libpng14.14.dylib (compatibility version 26.0.0,
 current version 26.0.0)
 }}}
