Comment(by baechler):
drkirkby, cp -a is a rough equivalent to cp -dpR - as -d is (according to
your post) not portable, this might be problematic, as -d copies symlinks
as symlinks, instead of copying the underlying file (this is what I
intended there).
Two more comments:
1) On Arch, the development headers for libreadline are always installed.
On openSuSE not by default.
2) I am thinking to extend this test further: Instead of testing for a
particular distribution, test whether libreadline.so.6 is installed and
the development headers are present - and in those cases, never build
libreadline. This way, only systems lacking libreadline or providing the
old libreadline.so.5 would have to build libreadline, all others would use
the system's library.
