This "alien store" is a nifty thing to have until the `cast --queue' operation
is over. One way to do this is to install the new spell version without
removing the old one (fake dispel), and "subtract" install logs to figure out
which files have to go to ultimately remove the old version. In this case,
libcrypto.so link would be overwritten by a new link, but libcrypto-0.9.7.so
would stay until the whole queue was cast. Only then those "legitimate aliens"
would be removed by `cleanse --fix' at the very end.
Two optimizations that I see are: (1) only do "fake dispel" for stuff in
/usr/lib, so that files in /usr/{bin,include} are removed at once; (2) make
"fake dispel" disabled by default, and only enable it for selected few spells.
