>Description:
Due to a bug in OpenSSL's c_rehash tool it can't be used on a NetBSD
system to populate /etc/openssl/certs with symlinks to the hash values
of certificates.

This problem has been [1]reported to the OpenSSL project as ticket #1901
and is fixed on the OpenSSL_1_0_0-stable branch.

[1] http://rt.openssl.org/Ticket/Display.html?id=1901
>How-To-Repeat:
Add some certificates to /etc/openssl/certs and run

$ c_rehash /etc/openssl/certs
Doing /etc/openssl/certs
sh: /root/openssl: not found
[...]
>Fix:
The following patch fixes the problem.  It's also available from
http://salmi.ch/~jukka/patches/nbsd/HEAD/crypto/dist/openssl/tools/c_rehash.patch
