[Eric] 2 flaws when follow this tutorial

[Jaime Seuma]

Hello iMath,

it is very kind of you to go through all the trouble of detecting the flaws
and the causes originated them.
I guess that I should have emphasized in the tutorial that it was made for
eric4; I wrote it before eric5 was released.
If memory serves, the procedures detailed in the tutorial used to work fine
with eric4; no errors whatsoever when running the project...

I haven't actually tried to run the tutorial from within eric5, but it is
possible that there are slight differences between eric4 and eric5 when it
comes to the structure of the project, etc.
All in all, I still think that the tutorial is useful since it provides
some guidelines for the newbie to work with the eric IDE.

Then again, maybe some day I'll have the time to update the tutorial for
the current eric5 version (?).

Regards,

Jaime
