Bugzilla Bug 166970

Installation broken when compile pl.o, looks like libgd headers do not setup
very well.

Reproducible: Always

Steps to Reproduce:
1. Prepare
echo "media-libs/ploticus ~* *" >> /etc/portage/package.keywords
echo "media-libs/ploticus gd -plpng" >> /etc/portage/package.use

2. Install
sudo emerge -vat media-libs/ploticus

I'm pretty sure that this happens because you compile media-libs/gd without
jpeg and png support(you have enabled gd support in ploticus) 
>[ebuild  N    ] media-libs/ploticus-2.33  USE="gd nls -X -cpulimit -flash -svg
----------------------------------------------  ^^  --------------------------

A solution is to recompile gd with png and jpeg flags enabled, and re-emerge
ploticus, so:
echo media-libs/gd png jpeg >> /etc/portage/package.use;
emerge gd;emerge ploticus;

I'm not a dev, but I hope I helped,

Panagiotis

Thanks Panagiotis, it works great!

Can we let emerge check the dependence of jpeg and png support if people
install ploticus with gd and png? An alert message from emerge can help peoples
like me locate this mistake.

Thanks  Panagiotis. The ebuild now checks this is the case. Thanks for the bug
report Xie.
