Installing rpm files needs root access. Many rpm archives put theyre files
into system directorys.
You can work on user level, logging in as ylzhao, and will do most
things somethere in /home/ylzhao/. So Your hardware should be protected
against viruses, while running dayly tasks.

You need an wxWindows-xrc package. If it is not precompiled (rpm) please
load the whole wxGTK-2.4.2.tar.bz2 and do an

 # bzip2 -dv wxGTK-2.4.2.tar.bz2
 # cd wxGTK-2.4.0
 # ./configure --with-gtk --with-opengl
 # make
 # cd contrib
 # ./configure
 # make
 # cd ..
 # su  ( login as root )
 # make install
 # cd contrib
 # make install
 # ldconfig
 # exit  ( exit the root mode )

... and wxWindows should be ready for use (hugin ;-) .

If Your browser is configured for that yes, but I would not expect this.
Go instead to the commandline and do
# rpm
You can read all options.
Without wxWindows-xrc it is not useful for hugin compiling.

I would expect it.
