It has got to be looking good, although I remember the time between 2.2 & 2.4 and 2.4 to 2.6 and all the waiting.
This came up a week ago in a buried-away section of the PClinuxOS forum and is a procedure for compiling Gimp on PCLOS. Its a long url from wordpress so I tinyurled it.http://tinyurl.com/7y6lx87
Worth a look just to see the effort these guys make to produce packages for ordinary users. It has just been updated with some screenshots of the Gimp 2.8 RC1 splash screen.
Although this for compiling Gimp, each one of the packages and there are dozens, needed for Gimp goes through a similar process. The site is a bit slow so don't overload it.
I have Gimp 2.7.5 running, still thinking about 2.8, but the whole process still amazes me, hats off to all the clever guys.
