The command "port file sbcl" tells you where sbcl's portfile is located.

If you modify the portfile, MacPorts will notice and clean the work  
area and start again. The distfile will not need to be fetched again  
because it was already fetched and is not stored in the work area but  
in the distfiles area.

No, it's fine.

Note that assuming your ports directory is synced using rsync, as it  
is by default, any changes you make to its contents will be wiped out  
when you next "sudo port sync".
