 I've tried to install libgcrypt from source using `configure.optflags=-g`
 : while the -g flag did show up in the build log, the resulting binaries
 are apparently stripped post-build. The RNG lock error message is printed
 at line 201 of file random-fips.c

 I tested this with "localhost" but also with a remote OS X VM; both
 systems run 10.9.5 . Connecting to Linux hosts running the x11vnc server
 works fine.
