[R-SIG-Mac] duplicate dylib ... libgcc_s.1.dylib

[Hans-Peter]

Thanks for your answer. What happened was, that 'R CMD CHECK helloC'
generated 3 shared object files at the following locations:
1) helloC/src/helloC.so
2) helloC.Rcheck/helloC/libs/i386/helloC.so
3) helloC.Rcheck/helloC/libs/ppc/helloC.so

It was a little unexpected that the shared object at 1) is for _ppc_
architecture even when I use an intel based MacBookPro.

Before checking the package I compiled/debuged the helloC/src/*.c code
with XCode and used 'R CMD SHLIB' to generate a helloC.so (which in
this case was for i386 and could be loaded by R).

Works fine now. Except for the warning message which is still the
same. But I can live with this.

Best,
Hans-Peter
