Dear Maintainer,

it appeared the maxima-sage fails to run at start on an uptodate Sid
environment. The command line

$ maxima-sage

gives

I get into this issue while I was fixing a FTBS bug reported against
the `sagetex` package.

Hello,

actually I think that my previous analysis is wrong.
The file maxima-index-html.lisp is indeed missing, but maxima-sage seems
to bypass this first error to rich an other one in some Python script.
Below might be the relevant part in the `build log`.

Thanks for the report, it's already fixed in the latest version.

Best,
Tobias
