Porting issues

[mwichmann]

A simpleminded test with just creating an env specifying the tool showed some issues with the current contrib set:

The following tools have the problem with the transition from SCons.Warnings.Warning to SCons.Warnings.SConsWarning: gob2, IDL, jal, kotlin, noweb, ProC, rest. Plus, from local branches, not merged yet - qt4/qt5 have the same issue.

These other tools failed due to missing Python modules:

lyx:

KeyError: 'PDF': from
...
  File "/home/mats/Work/scons.contrib/contrib/site_scons/site_tools/lyx/__init__.py", line 79:
    env["BUILDERS"]["PDF"].add_src_builder(lyx_builder

sip:

ModuleNotFoundError: No module named 'sipconfig':
...
  File "/home/mats/Work/scons.contrib/contrib/site_scons/site_tools/sip/__init__.py", line 57:
    import sipconfig

sphinx4scons:

ModuleNotFoundError: No module named 'sphinx.util':
...
  File "/home/mats/Work/scons.contrib/contrib/site_scons/site_tools/sphinx4scons/__init__.py", line 54:
    from sphinx.util.matching import patfilter, compile_matchers

The missing module errors (sip and sphinx4scons) I'm unsure about - modules of that name don't seem to exist at pypi.org.

The failure to find env["BUILDERS"]["PDF"] is user error, the simpleminded test didn't keep defaults so the pdf builder had not been initialized. Added, and it goes away (updated above)

sip is from PyQt. The stand-alone sip installation only installs executables and not a python module. See Problem importing sip after successful installation.
