OK. Understood.

I removed perl, tcsh, texlive-minimal as inputs, and tried

  guix environment --ad-hoc texlive giac-xcas --fallback -- xcas

I could preview the sheet using LaTeX. However, I sometimes got

  sh: pstopnm: command not found
  sh: pnmtopng: command not found

Not sure it is related.

Also, texlive-minimal is still in the closure, probably due to some
other input, so it doesn't reduce the size of the package.

Funnily, I broke Emacs indentation on purpose because other package
definitions in the file were disagreeing with it. I should have trusted
good ole Emacs.

This is because the test issue is related to a given release, i.e.,
a given `source' field. OTOH, `arguments' are for control over the build
process, which is not going to change anytime soon.

To put it differently, I put the temporary fix in `snippet' and the
persistent one in `arguments'.

Moreover, you suggest to merge the two fixes into a single phase named
`fix-makefiles', which, albeit correct, is less accurate than
`patch-bin-cp'.

Anyway, this is just nitpicking; I'm fine with all the changes you made.

Thank you for the review.
