#3 Rpm builder problem

[Anonymous]

When I tried to use RPM builder, it shouted
error:Error in Tcl scrpt "Child process exited
abnormally", which had [ok], [Skip Messages] and
[Cancel] options. I chose [skip messages]. The spec
file is generated but from that spec when I tried to
create RPM by giving command,
rpm -ba Myrpm.spec
that time at the last line it has given error
cd Myrpm-2.0-2
:Myrpm-2.0.2 No such file or directory
And didnt create RPM.I tried also by making changes to
that spec file accorbing to example found,
http://www.rpm.org/RPM-HOWTO/build.html
but of no use
