The last days I worked with GIMP (yes I must admit I am really impressed by it!). Once I checked the "InfoSociale" i found out that I am still using 2.4.0 RC3, well kinda outdated - aussi parler (thats the one with you get Ubuntu 7.1). I checked the Gimp homepage and saw, that there is already the final 2.4.3. But as usual i did not find the binary pour 64 bits. Due the fact that i had already the most of development stuff i decide to make one on my own.

You can download it from here:
GIMP 2.4.3_amd64

This is NOT for 32 bits! Use it on your own risque!
