As "CC=gcc" is a constant, I would write '("CC=gcc") here,
though admittedly this is largely a matter of taste.

Another problem: when cross-compiling, "gcc" will be a
compiler for the build system, not the host system (assuming
I got the terminology right).  Instead, write

     `(#:make-flags (list (string-append "CC" ,(cc-for-target)))
       ...)

(The quasiquote ` is important.)
(TODO to self: fix other packages that incorrectly set "CC=gcc" ...)

%standard-phases shouldn't be on a separate line here.

Prips has some tests, so don't delete this phase.

The ((bin-dir ...)) should be on the same line as 'let*'.

Why are you making bin/prips writable?  Shouldn't this be
(chmod bin-file #o600) instead?

‘Enhancement’ is rather vague and leaning towards marketing-speak.
I do not have an alternative suggestion however.

I looked at the source code and it seems prips is actually gpl2+.
