New blocks build into E110 "AttributeError: 'module' object has no attribute"

Hi All,

I’ve made some blocks on top of GRExtras, which are running without
problem
in my local machine (I build the whole GRExtras + new blocks). However,
when I build the same GRExtras into my USRP E110 and then, I run the top
block, I got the following error:

“AttributeError: ‘module’ object has no attribute”

It does not matter which new block I used, any of them have attribute.

Thanks for your help,

Regards,

Jose
