I don't have hands-on experience with AIX, but I am going to guess  
that you have a 32 bit version of unixODBC installed and that is what  
is being found on your system, raising the error. If you do have a 64  
bit version installed, I believe that the path is /usr/lib64, rather  
than /usr/lib. So you perhaps need to adjust the library paths for the  
RODBC package configuration and/or if not yet installed, be sure to  
install a 64 bit version of unixODBC.

Additional information is available in the RODBC package vignette,  
which is available online:


See Appendix A for Installation information.

BTW, for future reference, you might want to post to the R-sig-db list:
