Tim,
timKnapen:
Avenue33, did you try my project template with XCode 4? I think you can just open it as a normal project with XCode4.
I don't have a computer that runs Lion yet, so I can't test this.
The templates on Xcode 4 are totally different from and incompatible with those on Xcode 3.
Building fails with the following error message:
make
pic32-g++ -Wl,--gc-sections -mprocessor=32MX795F512L -Xlinker -T/Applications/Mpide.app/Contents/Resources/Java/hardware/pic32/cores/pic32/chipKIT-MAX32-application-32MX795F512L.ld -Xlinker -o/Users/avenue33/Desktop/Xcode_chipKIT/main.elf -Xlinker -M -Xlinker -Map=/Users/avenue33/Desktop/Xcode_chipKIT/main.map

collect2: ld returned 1 exit status
make[1]: *** [/Users/avenue33/Desktop/Xcode_chipKIT/main.elf] Error 1
make: *** [build] Error 2
Command make failed with exit code 2
On top of that, Xcode doesn't recognise the symbols and doesn't jump to the definition.
Enclosed the culprit.
My template for chipKIT is broken and I don't know why 
I hope you'll be luckier than me
