HKPS issue with static build of gnupg 2.0.26: checking whether curl is usable: no

[isdtor]

Not a gnupg problem. If the root cause for this behaviour is the
failure to link against libcurl, it's either the openssl ebuild or
openssl's own build system. I suspect the latter ...

# equery u openssl
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for dev-libs/openssl-1.0.1k:
 U I
 - - bindist       : Disable EC/RC5 algorithms (as they seem to be
patented) -- note: changes the ABI
 - - gmp           : Add support for dev-libs/gmp (GNU MP library)
 - - kerberos      : Add kerberos support
 - - rfc3779       : Enable support for RFC 3779 (X.509 Extensions for
IP Addresses and AS Identifiers)
 + + static-libs   : Build static versions of dynamic libraries as well
 - - test          : Workaround to pull in packages needed to run with
FEATURES=test. Portage-2.1.2 handles this internally, so don't set it
in make.conf/package.use anymore
 + + tls-heartbeat : Enable the Heartbeat Extension in TLS and DTLS
 - - vanilla       : Do not add extra patches which change default
behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the
meaning changes drastically
 + + zlib          : Add support for zlib (de)compression
