R devel - Feb 2001 - RE: [R] Re: failed rpm installation of R 1.2-1 (fwd) (PR#841)

I'm forwarding this to R-bugs.

In R 1.2.1 the file $R_HOME/bin/maketitle.awk is installed as an
executable. It should not be since it is just a set of awk commands,
not a script file that can be run from the shell (This is a change from
R 1.2.0 in which the file $R_HOME/bin/maketitle was a shell script).

This confuses an rpm utility called "find-requires" which scans all
executable files in an effort to determine the dependencies of 
the rpm package.
- binaries are scanned for the dynamic libraries they are linked against
- The heads of script files are scanned to see what language they
  are written in. In this case the first line of maketitle.awk is
  the awk command BEGIN, which is misinterpreted as a dependency for R.
