[arch-general] Missing gpg key?

[Sławomir Szczyrba]

Hello.

I try to recompile lib32-libgcrypt - because of this annoying error:
	libGL: dlopen /usr/lib32/xorg/modules/dri/radeonsi_dri.so failed
	(/usr/lib32/libgcrypt.so.20: symbol gpgrt_lock_lock, version
	GPG_ERROR_1.0 not defined in file libgpg-error.so.0 with link time
	reference)

and makepkg says :

[steev]/tmp/lib32-libgcrypt > LC_ALL=C LANG=en makepkg
==> Making package: lib32-libgcrypt 1.7.0-1 (Fri Jun  3 20:47:43 CEST 2016)

All keys refreshed:
gpg: refreshing 85 keys from hkp://pool.sks-keyservers.net
[...]
gpg: Total number processed: 84
gpg:              unchanged: 84

Missing key, or sth went really wrong?
