Unfortunately patch also doesn't provide any other details/hints on why
unbundling was needed and how was it handled. So I wondered if just it could
be built/shipped along?
wx.siplib is unbundled for multiple reasons:
1) It is Debian policy to not use bundled code, see [1].
2) The wxPython distribution doesn't include all of the source code for
sip, so it's not possible to build it. The upstream build process for
wxPython downloads a precompiled binary from the internet which is not
allowed in
Debian.
As far as how to address this I can think of a few options:
1) You can patch fsleyes to use the public sip module (provided by the
python3-sip package) instead of the wx.siplib module. In other words, you
would 'import sip' instead of 'import wx.siplib'.
2) I could try to look into providing some sort of wx.siplib wrapper
around the public sip module.
