Hi Konstantin,
"make cintdlls" does not have to be run with each ROOT installation.
making cintdlls takes time on some machines. The cintdlls need to be regenerated
only when the dictionary for the STL collections change. This does not happen
often).
However, the ROOT Makefile could be made more clever by detecting when
make cintdlls should be run. We will investigate this.
