Context is issue #615
The system is NetBSD 7.2, old but still supported.
It has a newer OpenSSL installed in /usr/pkg/
/usr/include/openssl/opensslv.h:# define OPENSSL_VERSION_NUMBER 0x1000115fL
/usr/pkg/include/openssl/opensslv.h:# define OPENSSL_VERSION_NUMBER
0x1000210fL
The old version doesn't support ALPN.
The symptom is that build is finding the new includes but linking with the old
libraries.
linking ntpd:
ntpd/nts_server.c.1.o: In function `nts_server_init':
/home/murray/ntpsec/raw/bob2/main/../../ntpd/nts_server.c:107: undefined
reference to `SSL_CTX_set_alpn_select_cb'
(and several others)
wscript contains:
elif ctx.env.DEST_OS == "netbsd":
ctx.env.PLATFORM_INCLUDES = ["/usr/pkg/include"]
ctx.env.PLATFORM_LIBPATH = ["/usr/lib", "/usr/pkg/lib"]
from ./waf build -v

There is no -L/usr/pkg/lib in there.
If I comment out the INCLUDES line is wscript ntpd builds. ldd shows it using
the old crypto.so
bob2/main/ntpd/ntpd:
-lcrypto.8 => /usr/lib/libcrypto.so.8
...
But now ntpd.so is broken:
File "/home/murray/ntpsec/raw/wafhelpers/bin_test.py", line 11, in <module>
import ntp.util
File "/home/murray/ntpsec/raw/bob2/main/tests/pylib/ntp/util.py", line 16,
in <module>
import ntp.ntpc
ImportError: Shared object "libcrypto.so.1.0.0" not found
./bob2/main/pylib/ntpc.so:
-lpython2.7.1.0 => /usr/lib/libpython2.7.so.1.0

-lpthread.1 => /usr/lib/libpthread.so.1
-lrt.1 => /usr/lib/librt.so.1
-lcrypto.1.0.0 => not found
This time, it does have -L/usr/pkg/lib

If I change the LIBPATH line to:
ctx.env.PLATFORM_LIBPATH = ["/usr/lib"]
and rebuild, I get the same error.
The -L/usr/pkg/lib is still in the load command.
Anybody know where it is coming from? I can't find the string /usr/pkg/lib
anyplace else in our code. I assume waf is doing some magic.
I'll be happy with either old or new version.
