> tcl-tclreadline.src: E: specfile-error sh: tclsh: command not found

This is caused by tclsh(1) being not available on your system. Usually this
is also case on builders until the build environment has been set up. Caused
by this line:

%{!?tcl_version: %global tcl_version %((echo '8.5'; echo 'puts $tcl_version' |
tclsh) | tail -1)}

If it makes you more happy, we can silent it by using instead:

%{!?tcl_version: %global tcl_version %((echo '8.5'; echo 'puts $tcl_version' |
tclsh 2> /dev/null) | tail -1)}

However this is just hiding the error message from STDERR.
