[R] Mac OS X 10.2.8 versus 10.3.4 package load failure

[Ingmar Visser]

Hello All,

I have built a package depmix and build a source package file from it for
distribution. I have done all this on the following platform:

platform powerpc-apple-darwin6.8
arch     powerpc   
os       darwin6.8 
system   powerpc, darwin6.8
status             
major    1         
minor    9.0       
year     2004      
month    04        
day      12        
language R     

When I install the package using the menu Packages > Install from local file
> From source package file (tar.gz) the package installs without problems.

However when I do the same another MAC OS X (10.2.8), I get the following
error message:

Error in dyn.load(x, as.logical(local), as.logical(now)) :
    unable to
load shared library "/Users/564/Library/R/library/depmix/libs/depmix.so":

Can anyone help me understand what the problem is here and how to solve it?
