This is a binary-only distribution of the Mocha tn5250 client. There are no known dependencies, but YMMV. An enhancement it has over net-misc/tn5250 is the function key support.
A quirky behavior of this client is during resize from 24x80 to 24x132 mode. It always sends the terminal window to the origin.
I would suggest net-misc as the package category.

The mocha-tn5250 ebuild
From the homepage:
The products can be tested before you actually buy them. During evaluation a
demo banner is displayed to help reminding, it is only a demo version. Aside
from this reminder, the products are fully functional. When you order, we will
send a software license code, which will disable the banner.
Also, looking at the tarball, this has not been updated since 2002.
Closing as WONTFIX.
