I have a post on my little blog about fitting a map to a globe without nasty pinching or discontinuities. Good for those who are as obsessive compulsive about realism as I wish I were.

Here you go. (http://astrographer.wordpress.com/2010/08/13/how-to-make-a-map-fit-a-globe/)

Comments here or on the site are welcome. Please rate this tutorial!

Nice :D

Know of any Gimp versions of the Flexify filter?

Try Matthew's Map Projection Software (http://www.users.globalnet.co.uk/~arcus/mmps/).
I'll try a new revised post with GIMP and MMPS. I'm looking forward to jury duty so it won't be too soon.

depending on just what input data you have
MMPS is not bad

the main issues are the correct mapping at and near the poles

gimp has a built in tool to remap to polar projection

this in combination with the gimp plugin "Resynthesizer"

the source code
https://github.com/bootchk/resynthesizer

you can then "fix" the area at the poles

or
use the built in tool "heal" to fix small areas
