why are the tests not passing? By manually looking at the files, the strings are present. Here is the output from helper script:

@peb-peb the /s and the periods in the strings need to be escaped with a \.

Hm, all of those version patterns look distinctly like pathnames. Does this work on other distro packages or just the one rpm? (It's mergeable either way, but we may want to flag it as being distro-specific the way we did with polarssl)

[peb-peb]

I was only able to find it for 2 distros (i.e. alt linux and netbsd) from https://pkgs.org/search/?q=libbpg. The pattern was consistent in these two.

[terriko]

Good enough for me. Let's merge it and if it turns out to be a problem, we can always adjust it later.
