You need to install them from source with those options in place.  A 
binary install won't include the line number information.

If you do your installs from the command line, you can set environment 
variable

R_KEEP_PKG_SOURCE=yes

but you can also do it from within R with the options above, using

install.packages("foo.tar.gz", type="source", repos=NULL)
