I'm reasonably new to R, and to stackoverflow, so apologies if I have not provided sufficient detail in my question below. Happy to provide more info if required
I run Windows 7 Professional (64 bit) and have R version 3.0.2 installed.
When I try to install devtools, I obtain
library(devtools)
Warning message:
package ‘devtools’ was built under R version 3.0.3 build_github_devtools()

I've searched for help on dependencies rversions and git2r but no luck so far.
Can anybody help please?
