The current version of fmtutil.pl contained in the
texlive-tetex-2015.101.3.0svn38001-97.1.noarch.rpm package is not working due
to two errors in the perl file:
- line 285: 
     my $uid, $gid;
  should be 
     my $uid;
     my $gid;
  or
     my ($uid, $gid);

- line 489: 
     texargs="\\batchmode \\input $texargs" if $eng eq "tex" || $eng eq "ptex"; 
  should be 
     $texargs="\\batchmode \\input $texargs" if $eng eq "tex" || $eng eq
"ptex";

This is probably an upstream bug, but I am not sure where to file it and anyway
I think it is better to fix the script in the rpm as it currently breaks the
functionality of the LaTeX installation.

Not yet tested in Leap, but probably it applies also there.
