Are you sure the Perl XML modules are needed at runtime and not at build
time (to build doc, for example?).

> +           python-numpy

If python-numpy is refered at runtime, you'd need to also add
python-wrapper as an 'input' I believe, since numpy is a Python
library.  One good way to verify if the dependencies are correct is to
run the package in a container with:

$ ./pre-inst-env guix shell -C plplot

and see if something fail.

Another telling data point to shake extraneous dependencies is looking
at the output of 'guix gc -R $(./pre-inst-env guix build plplot)'; if
python-numpy is not there (probably it isn't), but really needed at
runtime, then it'd need to be wrapper in the plplot command script.

Could you verify that the package works in a container, adding a wrap
phase if needed or removing the unneeded inputs?

Thanks!
