ncurses was only dispelled in the normal place when cast dispells it before
installing the new one.  The log produced by the failure and then success
was:

20051017:1615(+0000)    cast    ncurses 5.5     start   
20051017:1621(+0000)    dispel  ncurses 5.4     success 
20051017:1622(+0000)    cast    ncurses 5.5     failure 
20051017:1705(+0000)    cast    ncurses 5.5     start   
20051017:1711(+0000)    dispel  ncurses 5.5     success 
20051017:1712(+0000)    cast    ncurses 5.5     success

Seth indicated the spell knows how to protect bash during the upgrade, but
he hasn't given specifics yet.  ncurses' INSTALL does do a lot of backing
up libraries and such.
