I didn't expect that. But what did they answer when you asked the 
question "I am trying to compile your package, but I get an error. Here 
is my setup. Can you help?" Infact, if they provide you with source 
code, it is their responsibility to also provide you with a README file 
on how to set things up. I assume that on this entire mailing list with 
400+ people,  nobody can do that because nobody has the source code. If 
they don't have a README, ask for it. If they provide a README, but you 
struggle following the steps, ask them for clarification.

It depends. I suggest to reread my answer below.

Good luck,
