Ok, got it. Seems kind of obvious now that you say it. Thanks.

My next issue is that it won't install. I see this in the middle of
the build output:

starting phase `install'
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: *** [/usr] /usr: Permission denied
scons: building terminated because of errors.

As I understand it, every package has its own store directory, which
mirrors FHS, and all the package's files get installed there. I expect
Guix to install files to my package's store directory, but it looks
like it wants to install to the root filesystem instead. I might need
to add an `arguments` field to my package, but I'm not sure what to put
in it.

Also, my Sconscript has `env.Install('/usr/local/bin', 'doses')` for
its install target, which specifies the standard place to install files
in other OSes. Does scons-build-system assume some kind of different
usage, like maybe a relative path?
