| 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 ? 

Try the file src/Makevars as the Fine Manual (TM) "Writing R Extensions" clearly suggests.

| This should be done for the test routine and then for the final linking step of the package.
| Any help would be nice.
