Hi, I'm having some trouble wrapping a relatively simple C function using
Rcpp and inline and friends. This is my first time trying to use these
tools, so I'm sure I'm doing something wrong my immediate problem is
that I can't seem to figure out how to link against a library when
prototyping with
Hi Ken,
Thanks for your persistence with this!

Ken,
Here is an updated version of the 'secondExample' from that aforementioned
example file in Rcpp. It uses the plugin generator facility to override LIBS
which makes it work on my box. There may be a buglet in the RcppGSL package
and its definition of the default LIBS, or it maybe on my box.
