I needed to check a pdf from work tonight, and didn’t have a pdf viewer installed on my exherbo install. I checked, and someone had written an exheres for epdfview already, but there was a problem when I tried to install it.

$ sudo paludis -i epdfview -p

DepList additional requirements not met error:
  * In program paludis -i epdfview:

  * When adding PackageDepSpec 'app-text/poppler[gtk]':
  * Error searching for 'app-text/poppler[gtk]': additional requirements are not met

Additional requirements are as follows:
    * Flag 'gtk' enabled

I checked poppler, and for some reason I’d only installed it with the jpeg option, so I edited my use.conf to add gtk to poppler’s options, and ran paludis -i epdfview -p again. To my pleasant surprise I saw this:

$ sudo paludis -i epdfview -p

These packages will be installed:

* app-text/poppler::x11 [R 0.8.1]
    Reasons: *app-text/epdfview-0.1.6:0::x11
    -cairo -cjk gtk* jpeg
* app-text/epdfview::x11 [N 0.1.6]
    "A lightweight PDF document viewer using Poppler and GTK+ libraries"
    -debug nls

Total: 2 packages (1 new, 1 rebuild)

I checked with TPB and it’s a currently a feature, not a bug, so I say yay for progress, yay.
