I recall that my problem on Windows was related to having a number of stray versions of GTK+ installed. I went back and deleted all versions and reinstalled the latest GTK+ and that seemed to fix things. However, when I went to do any work of substance ggobi locked up and became unresponsive. Never did get it working right on Windows. Had much more luck with R/ggobi on Ubuntu 10.10.
I've just been setting rggobi up for our classroom. It seems that on Windows we now need to use Rgui in SDI mode to run rggobi without lookups. (That was not the case last year, so it might be due to the change in GTK+ version or it might be due to the change from XP to x64 Windows 7 on those machines.)
The rggobi binary on CRAN extras is statically linked against everything except GTK+, but the www.ggobi.org ggobi DLL needs both GTK+ DLLs and libxml2.dll (which needs iconv.dll and zlib1.dll). Late last year there was a problem in that GTK+ and libxml2.dll needed different zlib1.dll's, but AFAICS this is now resolved by using ftp://ftp.zlatkovic.com/libxml/libxml2-2.7.7.win32.zip and ftp://ftp.zlatkovic.com/libxml/iconv-1.9.2.win32.zip. (Unpack those and drop the DLLs into somewhere on your path, e.g. the GTK+ bin directory.)
We've had a lot of trouble over zlib1.dll: those prepared from zLib 1.2.3 and 1.2.5 are incompatible. The whole point of the '1' in the name is to change the name in that case! I suspect very few of those benefitting from Windows binary packages have any idea how much work goes into circumventing such issues.
