This may well be a FAQ (though I couldn't find any mention of it, my search-fu is weak...)
I've been trying to find an editor I can use consistently cross platform, and so far sublime2 has been good - nice on my OSX box and nice on my ubuntu boxes at home... (Not tried it on WinXX yet, but they tell me it works!)
At work, the boxes I'm currently using are RHEL 5.x (for various small values of .x), and when I try to spin up sublime2 I get a fail due to the absence (indeed total non-existence) of libgio on the RHEL systems.
I assume this is a reflection of the "innate conservatism" of the RHEL builds - i.e. they are ancient.
Is there a workaround to get me up and running, or are the RHEL boxes just too much of a backwater...?
