Those are all the current versions in the SBo repo but some of them are 
out of date and should be updated. Doing so is not entirely 
straightforward - here are the issues:

1. latest qwt is 6.1.2 (this is where I started since I needed it for a 
separate project). There is another problem with qwt - it installs its 
.prf & .pri files in the wrong location (this is due to qwt itself, not 
the maintainer) so that when building related software, qmake can't find 
necessary config & installation information about qwt. I'll email the 
maintainer separately about that.

2. libspatialite is now at 4.3.0a. Actually, wget of 4.2.0 returned 
"ERROR 404: Not Found.", so this should be updated regardless.

3. freexl is required by libspatialite (not sure why it doesn't appear 
in the list above) but the version 1.0.0i in the repo is not acceptable 
to libspatialite-4.3.0a. Latest freexl is 1.0.2 which is good for 
libspatialite so freexl version should be updated in the repo.

4. qgis itself doesn't immediately like the updated qwt-6.1.2. This is 
really because it has its own (now outdated) version of qwtpolar 
software. By configuring qgis not to use its internal qwtpolar and 
pointing to location of an up to date installed version of qwtpolar, 
qgis is able to build to completion. However there is no qwtpolar in SBo 
at the moment. I have a qwtpolar SlackBuild ready to submit (or for 
someone else to submit/maintain is they want it) but it depends on the 
changes to qwt mentioned in point 1 above.

All these issues are interrelated and should be fixed at roughly the 
same so that everything will keep working. Actually, its not working 
right now unless you happen to have an old version of libspatialite 
handy. I'll email qwt & qgis maintainers about potential changes. Can 
version updates of libspatialite and freexl be done directly in SBo 
repo, or will they need updates from maintainers?
