XDrawChem is a two-dimensional molecule drawing program for Unix 
operating systems. It is similar in functionality to other molecule 
drawing programs such as ChemDraw (TM, CambridgeSoft). It can read 
and write MDL Molfiles, and read ChemDraw text and binary files, to 
allow sharing between XDrawChem and other chemistry applications, 
and it can create images in popular formats like PNG and EPS. 

XDrawChem needs the openbabel library for which there is a build 
script at SlackBuilds.org.
