Build error with helm-rg in emacs25 and emacs26

[JohnC32]

When trying to byte-compile helm-rg and get see errors. Is this an issue with the way I'm byte-compiling or something else? I'm using helm-rg.el 2cac4b6 from Jan-30-2019

Repro on Linux (Debian 9):

mkdir helm-rg
cd helm-rg
dowload helm-rg.el 

emacs25 --version
GNU Emacs 25.1.1

emacs25 -batch -Q $LOAD_PATH25 -f batch-byte-compile helm-rg.el
In toplevel form:
helm-rg.el:265:1:Error: Unknown helm-rg-cl-typep pattern: (helm-rg-cl-typep keyword)

emacs26 --version
GNU Emacs 26.3
In toplevel form:
helm-rg.el:265:1:Error: Symbol’s function definition is void: helm-rg-cl-typep--pcase-macroexpander

where LOAD_PATH25 and LOAD_PATH26 contain -L /path/to/async -L /path/to/helm -L /path/to/dash.

I saw #6 which seems like a similar issue.

I realized the problem. I need to add -l helm-rg.el when building.
