to simply check the version and call that iem color function

I don't think so ; the interface of some functions has changed, so you need to be aware of the version at compilation time, and have to use this version at runtime. So I don't think you can build an external that would be compatible for both versions.

Thanks ! 
and thanks to Dan too, pointing me directly to the right direction !
But I realize that if I fix mknob for latest Pd it will become incompatible with older ones…

I believe the changes handle saving and loading based on the compatibility mode, so you should be able to simply check the version and call that iem color function in versions of pd less than 0.48.
