Bug: MacPorts 2.0.1 "too many levels of symbolic links"

[alantech@…]

After installing MacPorts 2.0.1 on a new machine (i.e. no prior version installed,) I get the following error messages in trying to access the port command for anything: couldn't read file "/opt/local/share/macports/Tcl/macports1.0/macports_fastload.tcl": too many levels of symbolic links

while executing

"source [file join "/opt/local/share/macports/Tcl" macports1.0 macports_fastload.tcl]"

(file "/opt/local/bin/port" line 37)

In examining /opt/local/share/macports/Tcl/macports1.0, I find that it is a symlink that points to /opt/local/share/macports/Tcl/macports1.0, in other words, a circular link.
