There only seems to be version 2.6.20 does this matter a lot?

Are you sure because at first I just did the make/make install and mdadm -V did tell me v2.6.2 but I don't believe it was installed properly because it didn't recognise my array nor did it make a config file, and cat /proc/mdstat said no file/directory??
