MacPorts Fail to Install Package/Port

[Gundala Viswanath]

Dear all,

I tried to install any port using MacPorts, using the following
command:

gundalas-macbook-pro:~ gundala$ sudo port install gnuplot


However it give such error:

Error: Target org.macports.fetch returned: couldn't read file
"/opt/local/var/macports/sources/rsync.macports.org/release/ports/_resources/port1.0/fetch/mirror_sites.tcl":
no such file or directory
Error: The following dependencies failed to build: aquaterm expat
fontconfig freetype zlib libiconv gd2 jpeg libpng ncurses ncursesw
pdflib readline
Error: Status 1 encountered during processing.

How can I resolve the problem?
