Well, I think this is a more general problem, and pkg-config does
the right thing by providing --libs-only-l and --libs-only-other.
The rule is:
* If you are linking with curl only, using the -L flags may be
* If you are linking with other libraries (e.g. readline), then
the -L flags must not be used, because they may conflict with
each other. The cleanest way to avoid such a conflict is to
have a global setting, e.g. via LIBRARY_PATH and ditto for
the include search path. So, the -L flags should be filtered
out with sed 's/-L[^ ]*//g', and with --cflags, the -I flags
should be filtered out with sed 's/-I[^ ]*//g'.
The attach patch fixes the problem here.
