pkg #1 upgrade: old version includes libfoo.so.1, new version includes
libfoo.so.2
pkg #2: scriptlet requires something from pkg #1, which uses libfoo.so.2
bang.
Only if libfoo.so.2 is in some non-standard path. If it is in
{,/usr}/lib{,64}, then when it won't be found in ld.so.cache, it will be
searched in the standard paths.
