[moved from R-help]

If you do R CMD INSTALL --no-test-load this will skip the part that is
hanging and you can try loading in stages (e.g. dyn.load on the RGtk2.so).
With '--no-test-load' it installs and ends normal. Loading per
dyn.load("RGtk2.so") works, just as dyn.load("RGtk2.so",F) and
dyn.load("RGtk2.so",,F). Unloading works, too.
Normal loading over library(RGtk2) within R does not work. R than is
hanging.
It seems the problem is not with the library itself?
I think this is rather technical for R-help, so maybe move to R-devel?
I moved to R-devel.
And can you check the RGtk2 version? A recent but not current version
(2.12.17?) did hang initializing Gtk+ on some platforms and Michael
Lawrence had to be involved.
I am using RGtk2_2.12.18.tar.gz for month now.

There are two packages I am not able to install: RGtk2 and rggobi.
For example rggobi builds fine and after that it wants to load:

At this point the install process is hanging, R utilises no more CPU
time. Same with package RGtk2.
Is this a known error? Please let me know if I can give more
information or try something different.
Well, those are exactly the two packages using Gtk+.
There is no known general problem, and as you could have checked from
the CRAN check pages, those packages install without problems on several
platforms. (Not Solaris, where ggobi does not install and RGtk2 requires
gcc, and not x64 Windows where both need to be patched.)
So it does look very like there is a problem with loading against the
Gtk+ system libraries on your system.
I think you are right. With previous versions of R (until R-2.10.x) I
did not have this hanging when loading RGtk2 ... And I am pretty sure
that I have no problems with gtk2 outside of R on my FreeBSD system.
In the meantime I found out that the reported loading error of rggobi
is a loading error of RGtk2, which fails (hangs). So there remains
only a loading error with RGtk2. (Because of that I changed the subject.)
After building/installing RGtk2, there are the following messages:

Is there a chance to find out what is wrong with loading RGtk2 on my
system? Unfortunately I have almost no experience with real debugging
methods on R. But of course I am willing to help and try out ...
