Hi,eclib-2014-05-14a-2 is already in debian, but upstream since released 2014-08-05. I packaged the new version and slighly modified the configure line to work around a bug which would have given issues with NTL 6.2.1, nothing fancy.
The repository is in debian-science's git: ssh://git.debian.org/git/debian-science/packages/eclib Thanks, Snark on #debian-science
