The error looks similar to the one I got for ruby-gpgme, when running
on Heroku:
https://gist.github.com/vovayartsev/a466aa82320b84f32b13
(the original issue: https://github.com/ueno/ruby-gpgme/issues/26)
where it seems to be failing in ttyname_r usage in GPGME.

I have not tried it by myself, but ArchLinux people tweak the mount
option of /dev/pts to work around this:
