linking modules - add needed libraries

Hi

Hopefully this is the correct mailing list. Sorry if not.

I am still fighting to install "shiny" on Solaris OS. For this I need the package 'httpuv' which makes troubles during linking.
R version 3.0.1 (2013-05-16) -- "Good Sport" is working well.

The compile steps result is below. I have more a general question. The problem is clear:
The symbol "sendfile64" is not found as the necessary library is not linked.
The file which should be linked is /lib/libsendfile.so
Therefore an additional string  "-lsendfile" should be added anywhere in a "Makefile" or another file.
But where ?
This should be done for the test routine and then for the final linking step of the package.
Any help would be nice.

Kind regards
Hans
