Summary: import error / restart
Initial Comment:
After trying to import rpy in python the only thing I got is a restart and a
not loaded import. In my specific case _rpy2051 (with R version 2.5.1
installed) could not be loaded. I also tried _rpy2041 (R version 2.4.1
installed) but I got the same effect. There is no error/exception message given.
I am using win xp sp2 and installed the required software (python 2.4, R 2.5.1,
Numeric-24.2.win32-py2.4.exe, pywin32-210.win32-py2.4.exe and
rpy-1.0-RC3.win32-R2.0.0-R-2.5.1-py2.4.exe).
I also have noticed that in rpy.py on line 119 the content of a try/except
block is only a 'pass', which probably should be replaced by line 117
'exec("import _rpy%s as _rpy" % RVER)'.

I've found the problem (at least in ubuntu):
When you (re)install python-rpy 1.0~rc1-6 it generates a _rpy2050.so in
your site-packages directory in python2.5, EVEN if your installed
r-based-core version is 2.5.1 (in this case the file should be named
_rpy2051.so)
I think that this bug is very easy to solve, but requires a new version of
the .deb file.

Got the same problem in my ubuntu gutsy 7.10 (with ipython), and I got the
r-base-core version installed as well. Here is the trace:
In [39]: import rpy
RHOME= /usr/lib/R
RVERSION= 2.5.1

I am also experiencing the above error (running Python 2.5.1 (Activestate
build), R 2.5.1, numpy 1.0.3.1). I tried changing line 119 from pass to
the exec statement and this had no effect on the error. I also tried:
"import _rpy2051" and this leads to a message that R.dll cannot be found
(RHOME is accurate). Running the same command in a python interpreter
started in R's bin directory (i.e., R.dll directory) leads to a total crash
out of python (like before)and a windows error (unlike before), with no
mention of R.dll not being found.
