[R-sig-Debian] rjags install on Ubuntu 10.04

[John C Nash]

I have been having trouble with rjags on Ubuntu 10.04


> library(rjags)
Loading required package: coda

Also I have tried

> dyn.load("/usr/lib/JAGS/modules-3/bugs.so")
Error in dyn.load("/usr/lib/JAGS/modules-3/bugs.so") :
  unable to load shared object '/usr/lib/JAGS/modules-3/bugs.so':
  /usr/lib/JAGS/modules-3/bugs.so: undefined symbol: fprec

After several uninstalls and reinstalls of jags and rjags, I did (as superuser)

apt-get remove --purge r-base-core
apt-get autoremove

then reinstalled R, then rjags (the Michael Rutter PPA is in my sources list), i.e.,

apt-get install r-base-dev
apt-get install rjags

(I used the dev to make sure I got some of the tools etc.)

No joy.

On crunchbang stattler linux (under VirtualBox), things loaded fine. I haven't tried
actual computations though. (This is a debian squeeze variant.)

Suggestions welcome, especially about the fprec symbol above. I am planning to upgrade the
10.04 to something else soon, probably Mint Mate, but wanted to wait a few more weeks to
avoid doing this when having to travel.
