I hope that you realize that with a LGPL license you cannot really
"control" anything - if somebody gets unhappy about the code for

all about - freedom to tinker. BTW, that is how the GPL osgCal fork came
to existence as well.
As far as I'm aware you can't relicense a LGPL library to GPL without
permission from the copyright owners. If osgCal GPL'd version is a
derivative of the LGPL version then this looks like a possible
copyright violation, unless it was sanctioned by the original
copyright owners.

LGPL licenced work can be relicenced as GPL. According to section 3 of
the LGPL (http://www.gnu.org/licenses/lgpl.html):
--- snip ---
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so that
they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in these
notices.
Once this change is made in a given copy, it is irreversible for that
copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the
Library into a program that is not a library.
--- snip ---
Although it is primarily for the purpose of including code from the
library in a GPL'd application, it also allows the creation of
derivative libraries licended under the GPL.
