I can confirm the error. It looks like an underlinking issue. The "quick" attempt to work around (version bump) did not help.

Not sure when I find time to look into the issue.

[vaeth]

Adding -ltinfo to LDFLAGS helped, but (at least with the current svn version) lisp errors occurred.

I am sorry, I will probably not be able to fix the package in a reasonable time. I will leave it in the tree for others to develop, but I do not have the time to support the ebuild anymore.

[Alessandro-Barbieri]

I'll get a look

[Alessandro-Barbieri]

Which version have you tried?

[vaeth]

I pushed now the (not yet working) ebuild to the repository.

[Alessandro-Barbieri]

I mades some fixes but it fails at installing the Emacs mode

[vaeth]

This sounds easy enough that I might find time to fix it. (Though I do not make any promises: I do not use reduce, and my spare time has become very low for many reasons.) If you like, upload it somewhere (e.g. as a PR) and I might look at it (perhaps in 1-3 weeks).
