Bug#699071: libm4ri dependencies lack libpng

[Alexander Dreyer]

Package: libm4ri
Version: 20120613-1

libm4ri is built without png support. This is causes by the fact, that 
libpng is not mentioned in the Build-Depends:/Depends: sections of 
debian/control.

So, configuring deactivates png support at all:

checking for PNG... no
checking for png_create_write_struct in -lpng... no
checking for png_create_write_struct in -lpng14... no
checking for png_create_write_struct in -lpng12... no
checking for png_create_write_struct in -lpng10... no
configure: WARNING: Can not find a usuable PNG library. Make sure that 
CPPFLAGS and LDFLAGS are correctly set.

Installing libpng fixes this issue, of course. But automated builds need 
correct dependency lists.

Best regards
