A new version of the listings package is available - its mainly a bugfix release with some additional language definitions.
Created attachment 39187 [details, diff] diff to previous listings-1.2.ebuild The way portage handles SRC_URI seems to have changed - i made minor adjustments to be able to download the package from the original source. Apart from that its just a plain version bump without any problems AFAICS.
Added to CVS. Thanks.
