So enabling prelude at build time will pull in the libprelude package.
Runtime wise it does nothing unless enabled in the config file. Doesn't
look too bad.
The libprelude seems to be under GPLv2 (there parts of the library under
LGPLv2+ but my understanding is that there are parts of the library under
GPL). There is no OpenSSL license exception and my understanding is that
we need this even for dependencies. See also #924937 where this
currently discussed for other packages. I don't see that I can enable it
at this time.
There is an upcoming OpenSSL 3.0 is under the Apache-2 license which
still doesn't work unless the license is v2 or later. The alternative
would be an OpenSSL license exception. Upstream seem to have moved from
OpenSSL to GnuTLS due to license issues instead of granting an excpetion
and be done with it. See
