Comment (by mzryz):

 Just an update @kencu @cjones051073 my machine just successfully finished
 building gcc7 and updating all its ports. I think the issue was a
 combination of me having a strange combination of un-upgraded ports, the
 custom repo and also I found I hadn't selected a default gcc. I selected
 default gcc as mp-gcc7 and re-ran all my updates last night, and today
 they're all done.

 Thanks again for helping a noob.

 FYI kencu - without LeopardPorts many people wouldn't be able to use
 MacPorts at all with PPC, honestly the discovery of LeopardPorts enabled
 many in the community to use this amazing system. Even now my machine is
 working fine with it & I don't think the repo was to blame, just my silly
 configuration.
