packages contains files like "base.scm" corresponding to the module
(gnu packages base).  However, now there are two (gnu packages base) --
the base from the guix you run, and the base from ./.  Additionally,
"base.scm" has a module (gnu packages base) so Guile expects it to be
located in ./gnu/package/base.scm instead.

Instead, try:

/home/bost/dev/guix
# do this inside a "guix shell -D guix" or whatever you use
# to set up a Guix development environment  
$ make && time ./pre-inst-env guix build openjdk

(also, don't do --check -- check is for verifying that the build was
reproducible, but it's a new package definition, so Guix doesn't have
anything to compare it against).

Looks like Guix didn't detect the new package definition, otherwise
you'd see ‘The following packages will be build’ or the like.

is addressed, WDYT of (replace "openjdk" openjdk)?
