Thanks to Jonathan and Oleg for their suggestions/comments. Their
responses are added at the end of this email.
I tried Oleg's suggestion of giving me write permissions on
/usr/lib/R/library. This didn't seem to work (I tried various
combinations of changing permissions and ownership but nothing worked).
Anyway, before changing permissions the library would not work when R
was fired up as root. I am by no means a linux/unix expert and maybe
there is some method of giving me write permissions that would have
solved the problem.
Jonathan was right that his was essentially a different problem. I
already had fftw2 installed.
My (heavy-handed) solution was to bite the bullet and re-install fedora
core 6 from scratch. (Apparently the upgrade from fc3 does not work as
well as back up + fresh install.) After running yum update, I then
installed R by clicking the relevant R RPM in CRAN. I subsequently
installed fftw2 and fftw2-devel (using "yum install package_name") (the
development package is needed) and installed rimage using
install.packages("rimage") within R and everything is now fine. Note
that it is also necessary to install libjpeg and libjpeg-devel if you do
not already have it.
I hope that this helps others that want
I am looking forward to playing with Oleg's EBimage package.
Thanks again and Happy New Year to all!
Cheers
John

Cannot help you much with that as the thing seems to compile normally.
As you use a global R installation, try giving yourself write
permissions in /usr/lib/R/library, this might help. Otherwise, try
installing R from source in your home or elsewhere where you have all
write permissions and check it again.
Anyway, I wanted also to advertise my package because you use rimage:
http://bioconductor.org/packages/2.0/bioc/html/EBImage.html
The difference is - it supports up to 95 image formats and implements
many image processing methods. In fact you can combine this with
functions from rimage. If interested, go for a development version above
and it works on Fedora 6 Zod and 2.4.1 - did try just today.
Best regards,
Oleg
