I am playing with the idea of creating a compiled version of perl with loads of modules that can be installed on a Linux system and used similar to what Strawberry Perl provides for Windows but I have an issue:

After a relocatable perl 5.10 built using -Duserelocatableinc both the scripts that come with perl and scripts that are installed by modules have the following lines at the beginning of the file:

bin/cpan that comes with perl: 

#!/tmp/xl/perl-5.10.0-xl-03/bin/perl
    eval 'exec /tmp/xl/perl-5.10.0-xl-03/bin/perl -S $0 ${1+"$@"}'
    if $running_under_some_shell;
#!/usr/bin/perl

[download]
bin/padre that was installed later: 
#!/tmp/xl/perl-5.10.0-xl-03/bin/perl 

eval 'exec /tmp/xl/perl-5.10.0-xl-03/bin/perl  -S $0 ${1+"$@"}'
    if 0; # not running under some shell

[download]
Once I move the whole installation to some other place these will stop working and I'll have to write /path/to/new/location/bin/perl /path/to/new/location/bin/cpan I guess it could be fixed by running an update script after relocating the code but is there a better way that does not require making changes after moving the files?
