Just wanted to mention that I saw the same behavior with a package or
two, and found the same workaround (copying libs to the 2.12 tree).

Subject: [R-SIG-Mac] Packages deldir, class and gpclib fail to load in
R 2.13.0

Hi,
I've been running rgdal, RColorBrewer, maptools, classInt, spdep,
gpclib, raster, zoo, cluster and lattice in R2.12 on Mac OSX 10.6.7 for
the last 6 months with no problems. Today I installed R 2.13.0, and
downloaded the latest versions of the above packages. Most of them load
without problems, but class (a depend of classInt), and deldir (a depend
of spdep) failed to load. The error message is of the form:
-------------------------------
Loading required package: class
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object
'/Library/Frameworks/R.framework/Versions/2.13/Resources/library/class/libs/x86_64/class.so':
dlopen(/Library/Frameworks/R.framework/Versions/2.13/Resources/library/class/libs/x86_64/class.so,
6): Library not loaded:
/Library/Frameworks/R.framework/Versions/2.12/Resources/lib/libR.dylib
Referenced from:
/Library/Frameworks/R.framework/Versions/2.13/Resources/library/class/libs/x86_64/class.so
Reason: image not found
Error: package 'class' could not be loaded
-------------------------------
The problem seems to be either the package is looking in the wrong place
(a subdirectory of 2.12 instead of a subdirectory of 2.13) for the file
libR.dylib, or the install of R failed to put the files that package
class needs in the 2.12 directory. In the case of deldir, the errant
file is libgfortran.2.dylib.
I can get package class to load without error by taking a copy of
libR.dylib from the subdirectory of 2.13 and putting it in the
subdirectory of 2.12 where class expects it to be.
I'm concerned this might be a stupid short-term fix, as calls to the
functions in class might also fail due to other files not being in the
expected places.
Can anyone suggest any leads to other approaches I could take to get
these previously trouble-free packages to behave themselves in R 2.13?
Thank you.
