As of a couple of weeks ago, Yahoo changed their web site such that Finance::Quote is no longer able to retrieve foreign exchange quotes. This bug has been reported upstream as number 46006. In particular, this keeps GnuCash from updating currency quotes. I will attach a patch and e-build update that should fix this issue. The patch has been submitted upstream as well.

Created attachment 192723 [details, diff] Updates e-build to include patch.
