R-beta: $PERL in configure

[Gordon Maclean]

One minor request, on the subject of installation scripts.
Could you change "configure" to use the value of $PERL,
when it checks for the version number?  

  PERL_VERSION_NUMBER=`$PERL -v | sed -n 's/^.*perl.*version \(.\).*/\1/p'
  
rather than:

  PERL_VERSION_NUMBER=`perl -v | sed -n 's/^.*perl.*version \(.\).*/\1/p'`


On our systems, plain perl is version 4, and we must set PERL to "perl5"
in config.site. Then the above version check fails to detect version 5.

I believe that the value of $PERL is otherwise propagated to the build scripts.

Thanks,

Gordon
