 [wiki:ProblemHotlist#compiler| building using another compiler], i'm

Comment:

 Both logs show the error:

 {{{
 error: invalid use of incomplete type 'struct png_info_def'
 }}}

 which indicates an incompatibility with libpng 1.5. The first thing we
 should try is to [ticket:33798 update the port to a newer version].
