[R-SIG-Mac] dyn.load() fails with R 2.6.0

[Tiago R Magalhães]

Dear Mailing list, Enrico, Simon,

After installing to R.2.6, I got the same exact problem when installed 
the SNPassoc package; it seemed to be looking for 2.5 (

I ended up uninstallling R and reinstalling it from scratch; now it's 
working.

Cheers,
Tiago

Enrico,

Yes, you seem to be mixing R versions when compiling your code. I  
suspect that you have an older R on your PATH so you are compiling  
for the wrong version of R. Please double-check your R versions. If  
the problem persists, please post the full output of the compilation  
and the result of otool -L test.so

Cheers,
Simon
