Was that with --tag=CXX?

Yes, it only later picks up the other paths that are set in $postdeps
for the CXX tag, because it parses $postdeps in the wrong order.

Hmm.  LD_LIBRARY_PATH is not something that is enforced to be equal for
all users of a system.  A library you compile now with some setting for
LD_LIBRARY_PATH may not run for the next user, with her different
setting, nor for you from another shell.
