hi, same here adding inherit flag-o-matic and append-flags "-lm" to the ebuild fixed it for me... markus
Exactly the same error here. @markus : I'm not too hot on writing/tweaking ebuilds, could you indicate line numbers for where these should be inserted, I'll give it a go in a local overlay and if it works then upload a modified ebuild as an attachment?

This looks like weak symbols. I'm going to wait for the maintainer to re-write.

Created attachment 357260 [details, diff] Patch solving the underlinking problem
Patch applied to Portage. Closing.
And looks like the fix is already in upstream repository as well: http://sourceforge.net/p/hugin/autopano-sift-c/ci/4cebf88164c434aba3c635d46534ad3247db2e5f/
