Time is definitively part of the answer the other part being the
challenge of rebuilding the repo once in a while when necessary.

R can be coupled with java as it can be with C/C++/fortran &so on, I
*assume* that this is what was done in this package (again, *assumed*).
If it is not the case, then for sure it should not be this way and it
should rely on system libraries.
R-repo is/was aiming at automatically generated RPM which mean that a
number of them are not 100% valid. At least it gives us a basis for
further improvement.
I have to say that from my side time is truly limiting and the situation
won't change (it will even get worse) with the fact that I am starting
the last year of my PhD but at least this time everything is publicly
available on github if there are people interested in the
maintenance/development of the project.

To be honest, I do not know, but I am not sure install.packages runs the
tests and thus it likely doesn't run into the circular dependency
problem which are most of the time of the type: A requires B which
suggests A (or similar).

There are no form of license check done atm in R-repo and it doesn't
rely on a central database.
The dependency tree is built by parsing the PACKAGES files from the
different repository.
The R-repo-utility [1] contains the script doing the work (building the
tree, building the RPMs, checking for updates and so on).
Let me know if I can be of any help.
