If you really care about building it from source instead of simply verifying the signature, you should at least do it yourself.
I don't see the reason behind letting soemone else access your computer to compile electrum from source.

You could either use the guide together with a tutorial on how to set up a virtual machine and therefore compile it yourself (which kind of is the reason to compile something yourself) or just verify the signature to be sure you are not using a malicious version of electrum.
