Hello,

Recently updated Ubuntu to 10.04, I have installed the r-base and
r-base-dev packages from CRAN with

sudo apt-get install r-base

But now when I want to start R I get the following error:

gpet...@definetti:~$ R
/usr/lib/R/bin/exec/R: symbol lookup
error: /usr/local/lib/libreadline.so.6: undefined symbol: PC

That .so file is in /usr/local/lib and did not come from an Ubuntu package.

Yes. Not sure where this came from, but make sure that libreadline 6.1-1 is installed via apt or synaptic. You may also have other versions of libreadline.so or libreadline.so.6 linked to this somewhere else on the system, so make sure nothing links to this file.

Any clue??? Has anybody seen that before? I have tried to reinstall the
readline libraries, both as a ubuntu package and from sources, but the
error did not go away....

Thanks in advance,
Giovanni
