This npm package requires FontForge 2 which is not available on the base repo of Centos 6 (the current one is very outdated...dating to 2009!). Looking for prebuilt RPMs proved difficult, if not pointless so I decided to take a shot in compiling from sources. Since compiling FontForge 2 on Linux is a royal pain in the ass, I hope that this document will save you some time (read hours!):
