Well, no, I guess not:

We can't have nice things. It's looking like I either need an ugly patch
to RC or an ugly pile of lua in the spec. Sigh.
Sorry, just noticed the gist of this thread. Are you trying to replace a directory with a symlink? Take a look at gallery2:
Example.
In %install:
#remove bundled Smarty.
rm -rf lib/smarty
ln -s ../../php/Smarty2 ${RPM_BUILD_ROOT}%{installprefix}/gallery2/lib/smarty
#remove bundled Smarty.
rm -rf lib/smarty
ln -s ../../php/Smarty2 ${RPM_BUILD_ROOT}%{installprefix}/gallery2/lib/smarty
Then in %post:
if [ -L %{installprefix}/gallery2/lib/smarty ]; then
rm -f %{installprefix}/gallery2/lib/smarty
fi
if [ -d %{installprefix}/gallery2/lib/smarty -a ! -L %{installprefix}/gallery2/lib/smarty ]; then
mv %{installprefix}/gallery2/lib/smarty %{installprefix}/gallery2/lib/smarty.rpmbak && \
ln -s ../../php/Smarty2 %{installprefix}/gallery2/lib/smarty && \
rm -rf %{installprefix}/gallery2/lib/smarty.rpmbak
fi
if [ ! -L %{installprefix}/gallery2/lib/smarty ]; then
ln -s ../../php/Smarty2 %{installprefix}/gallery2/lib/smarty
fi
if [ -L %{installprefix}/gallery2/lib/smarty ]; then
rm -f %{installprefix}/gallery2/lib/smarty
fi
if [ -d %{installprefix}/gallery2/lib/smarty -a ! -L %{installprefix}/gallery2/lib/smarty ]; then
mv %{installprefix}/gallery2/lib/smarty %{installprefix}/gallery2/lib/smarty.rpmbak && \
ln -s ../../php/Smarty2 %{installprefix}/gallery2/lib/smarty && \
rm -rf %{installprefix}/gallery2/lib/smarty.rpmbak
fi
if [ ! -L %{installprefix}/gallery2/lib/smarty ]; then
ln -s ../../php/Smarty2 %{installprefix}/gallery2/lib/smarty
fi
Then in %files
%ghost %{installprefix}/gallery2/lib/smarty
%ghost %{installprefix}/gallery2/lib/smarty
Pretty? Nope. Overkill? Maybe? Reliable? So far.
This was the product of work by myself, Rex Dieter, and some serious pain. <shudder>
moodle has similar examples, including one we had to reverse.
