[gentoo-amd64] libpng link depend problem

[Benny Pedersen]

openjpeg and php links runtime to libpng, why when there is no png use 
flag ?

upstream bug ?

emerge -pv --depclean libpng shows here currently openjpeg and php

is it not possible to get rid of png ?

For PHP, look at the ebuild, especially its DEPEND variable. It depends
on libpng if cjk, exif, truetype, xpm or gd are activated.

For openjpeg, the answer seems to be "No" as the dependency is
unconditional. There doesn't seem to be a flag in upstream's build
system, either.

i had mupdf depends on this one

and netpbm was linked to libpng without ebuild dependice, discovered 
this when there was no depends on libpng and tryed revdep-rebulding

so i will make a bug for netpbm

if something depends on something hard (ie: no choice, must have, blabla) 
there is no useflag.

Which means: there is probably no bug.

i am not sure what you are talking about, since there is a useflag for png in 
netpbm.

wish i had checked before remerge that my local netpbm missed depend, 
but its resolved here now
