We've seen this issue but I thought we'd fixed it.
Which version of master did you do this with? This was supposed to be
fixed by
http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=c281cd149bdbce29fc69cb34c65c4295cfed2060 and http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=534c4d0f1e287d0ac82504b273a5497d3457582a
If you're still having problems, please strace the above python command
and see where its looking for terminfo...
Cheers,
Richard
