Comment(by macosx12345@…):

 I suggest the following changes (improvements?) to the script above:

 - use portfile=`port file $lib` instead of portfile=`locate $lib/Portfile
 | grep -v old` (then, there is no need to rebuild the locate database
 since we don't use locate)

 - do not use locate to find the sources.conf file, but rather some trick
 like:
         portprefix=`port dir wget | sed -e 's/var\/macports\/sources.*//'`
         sourcesconf=$portprefix/etc/macports/sources.conf
 (and make sure wget is installed before calling checksourcesconf() )
  Indeed, if there are several versions of Mac OS X on the hard disk (say
 10.4 and 10.5), using locate we are going to find the sources.conf file of
 the first one, which might not be the running one (I had the problem). I
 think the trick hereabove is more robust.

  By the way, suggestion for the maintainers of MacPorts: give a way to get
 the prefix from the port command (something like "port prefix" would
 return "/opt/local") or, maybe better, add a command like "echo" that
 expands the global TCL variables used in portfiles instead of the
 pseudoports (if this command is "tclexpand", then "port tclexpand
 '$prefix'" would return "/opt/local").

 - do not assume that the local repository is in $HOME but read the
 sources.conf file to find where it is (and complains if there is none, as
 did the script). The best would be to check all local repositories listed
 in sources.conf and see if there is one where the user has write access
 but... Here we assume there is only one.

 - accordingly, make all operations (cp, patch, and so on) in $localrep
 instead of explicitly using $HOME .

  Then, the script looks like:
