R help - Mar 2004 - where is OOP?

Hi there,

Installation error was given when I tried to install pmg (Poor mans
GUI) http://wiener.math.csi.cuny.edu/pmg/index.html.

$ LANG=C sudo R CMD INSTALL pmg_0.6.tar.gz 
* Installing *source* package 'gtkpmg' ...
** R
** save image
Error in library(OOP) : There is no package called 'OOP'
Execution halted
/usr/lib/R/bin/INSTALL: line -116: 20554 Broken pipe             cat
"/usr/lib/R/library/gtkpmg/R/gtkpmg"
ERROR: execution of package source for 'gtkpmg' failed
** Removing '/usr/lib/R/library/gtkpmg'

It may be solved if I install OOP in advance, but the OOP library was
not found.  Does anyone tell me where I can download it?

Hi,

This is self-response.  I found OOP on http://www.omegahat.org/OOP/.
However, further error was given.

$ sudo R INSTALL OOP_0.4-2_R.tar.gz 
* Installing *source* package 'OOP' ...

gcc -shared -L/usr/local/lib -o OOP.so RtreeApply.o

Dose anyone succeed to install OOP in R 1.8.1?
