Anyways, I just emerged gimp, and I'm having problems saveing (and opening) .png files. When I try, it gives me this error message:

[error] saving '/home/me/example.png failed: Plug-in could not save image
[/error]

i dont know about emerge -- but it is unclear here that there was problems opening png images up.

if there is only a problem saving them, perhaps it is a permission problem. if there is a problem both opening and saving pngs, then there might be something wrong with your png libraries.

is it possible to just build it (even once as a test) without "emerge"? meaning, run through the basic make tools without the aid of the package handler? then it would be easier to determine if it is gimp or your distribution.

As another gentoo user, chances are that the original poster didn't have png specified in the USE variable, so when gimp was emerged, png was not set as a dependency, and thusly the png libraries were not included at compile time.

From the gimp-2.0.2 ebuild file, the following USE variables are used:
doc python aalib png jpeg tiff mng wmf gimpprint gtkhtml mmx sse X altivec debug

So if you want support for all the stuff gimp has to offer, I'd suggest placing most of those into your global USE variable (although, you might want to leave off debug if you're just using gimp).

I went ahead and compiled it from source, an d I'm still getting this error. What libs do you think I need to replace?

it has got to be the png library then. did you follow the other advice? it was given by someone familar with emerge and its ways.

GIMP won't even compile if libpng is missing (unless you explicitely tell configure that you want a gimp without PNG support.
