Your code works for me, so I think there is still a problem on your system
configuration.
The error is about the C function `CVodeCreate`, not the Julia function
with the same name, and apparently Julia finds the sundials library, but it
does not contain the function.
Try to run `print(Sys.dllist())` after running your test code to see what
libraries are actually loaded. When you know what library gets loaded, you
can inspect the library with eg. `nm /usr/local/lib/libsundials_cvode.dylib`,
and see if you can find the `CVodeCreate` function.
