I'm not familiar with the issue you're seeing, but the existing and new code
are looking for 3 int()s separated by periods. If your recipes have the string
"4.9-rcX" then I'm guessing there might still be an issue since the third
int() will be "-rcX" in your case. If this is true, you'll need to take a look
at where "int(min_ver[2])" is used further down in that bbclass file.
