The problem is that I cannot install rgdal, and I need it. Rather
desperately.
I do:
install.packages("rgdal",lib="/home/rolf/Rlib")
and get the error message:
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/home/rolf/Rlib/rgdal/libs/rgdal.so':

Error: loading failed

Since I (in my desperation) cross-posted to r-sig-debian and r-help, I
am sending this "SOLVED" message to both lists.
The solution took a long while to find, but in the end it was very simple.
Quite a while back I was having problems with installing some package
(I *think* it was one of my own packages, hmm.discnp), and someone (the
details are lost in the mists of time) advised me to create a directory
".R" in my home directory and in it place a file "Makevars" containing
the lines:
FCFLAGS = -g -O2 -mtune=native -fbounds-check
FFLAGS = -g -O2 -mtune=native -fbounds-check
PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
This solved the problem that I was having at that time. I had long
forgotten the directory ".R" and *that* was what was causing the problem.
A *very* clever and knowledgeable young Linux whiz, who kindly agreed to
help me with this problem, eventually tracked down the fact that it
originated from ".R". When I removed ".R", the problem with rgdal (and
problems with several other packages, that subsequently surfaced) went away.
My system is now humming away smoothly.
Thanks to everyone who (futilely!) attempted to help me out.
cheers,
Rolf Turner
