[bug-recutils] building: recutils bash builtins/readrec.so; "howto" somewhere?

[recutils]

Greetings:

I'm on fedora 26. The fedora recutils package  does not have recutils bash 
builtins,
like readrec, so 

    "enable readrec.so readrec" 

fails.

In order to build recutils from the tarball, I need to set up several bash 
header directories.
I got started on this by untarring bash source code, and made some progress, but
punted after about 1 hour - I really do not know what I am doing.

Is there a "how to" build recutils with 'bash builtins' somewhere?

thanks/regards
