Please provide `emerge --info`, `emerge -pv libvncserver` and the complete build.log, as mentioned on the bug reporting site.

Attach those, please.

I just hit this same issue on my machine, and was able to trace it down to the --disable-gcrypt option passed to econf.  If USE=crypt is set, the package compiles sucessfully.

I will attach a failing compile log with EXTRA_ECONF=--disable-silent-rules (to ensure that the full command lines are shown).

[Comment 6 Jeroen Roovers (RETIRED) 2012-06-19 14:58:34 UTC]

USE=gnutls should make it DEPEND on dev-libs/libgcrypt, too, I guess.

[Comment 7 Mike Gilbert 2012-06-19 15:29:49 UTC]

Hmm... the gcrypt stuff is a bit hairy. There are two flags involved:

  --without-gcrypt        disable support for gcrypt
  --without-client-gcrypt disable support for gcrypt in libvncclient

Using --with-gnutls and --without-gcrypt together will cause under-linking of libvncserver.so.

While I'm poking at this, I want to look into that client-gcrypt flag to see if it is useful.

[Comment 8 Mike Gilbert 2012-06-19 16:22:33 UTC]

This should be fixed in 0.9.9. It probably needs to be addressed in 0.9.8.2-r2 as well.

+  19 Jun 2012; Mike Gilbert <[e-mail]> -libvncserver-0.9.8.2.ebuild,
+  libvncserver-0.9.9.ebuild, metadata.xml:
+  Force gcrypt when gnutls is selected, bug 420803. Add openssl dependency.
+  Rename crypt and no24bpp use flags to gcrypt and 24bpp.

[Comment 9 Mike Gilbert 2012-06-19 19:13:07 UTC]

0.9.8.2-r1 seems to be fine.
