I would like to share a lightweight solution based on groff.

I have assembled an ob-groff.el file mostly coping the essential parts 
from ox-asymptote.el.

Once this is done, you can C-c C-c a groff source block and get the link 
to the output file in the same buffer.


Notes:

- Tested with emacs 24.5 and 25.0.92, org-plus-contrib ELPA 20160321, on 
OS 10.10.5.

- groff last version 1.22.3, which has -D<encoding> option; remove from 
:cmdline if your groff version is < 1.22.3

- pdf output is hardcoded in ob-groff.el; you can remove from there and 
add to :cmdline to get .ps or .dvi files if you prefer.

- Groff examples are from:

http://pipeline.lbl.gov/code/3rd_party/licenses.win/groff/1.19.2/html/mom/letters.html

I hope not to have forgotten acknowledgment to some of those wonderful 
people that write and share FOSS.

Thanks all!
