>Description:
After upgrading tshark-lite to use libgcrypt-1.4.3, ssl decryption (with private key) is broken.  Using portdowngrade(1), I reverted back to libgcrypt-1.4.1_1, and got ssl decryption working again.

Here's the versions of the relevant ports where ssl decryption DOES NOT work:

$ pkg_info | egrep 'libgcrypt|gnutls|tshark'
gnutls-2.6.3        GNU Transport Layer Security library
libgcrypt-1.4.3     General purpose crypto library based on code used in GnuPG
tshark-lite-1.0.5   A powerful network analyzer/capture tool (lite package)

And here's the versions of the relevant ports where ssl decryption DOES work:

$ pkg_info | egrep 'libgcrypt|gnutls|tshark'
gnutls-2.4.2_1      GNU Transport Layer Security library
libgcrypt-1.4.1_1   General purpose crypto library based on code used in GnuPG
tshark-lite-1.0.5   A powerful network analyzer/capture tool (lite package)

Also, the specific problem with ssl decryption that I had is basically identical to the one described in the following URL:

http://wireshark.osmirror.nl/lists/wireshark-dev/200707/msg00244.html
>How-To-Repeat:
As far as I know, it should be repeatable provided one installs tshark-lite (or tshark, or wireshark) from a currently up-to-date ports tree.  I ran tests on two amd64 machines (one 7.0-RELEASE, one 7.1-RELEASE), and provided tshark-lite was build to use libgcrypt-1.4.2, ssl decryption broke.
>Fix:
Use portdowngrade(1) to downgrade libgcrypt to 1.4.1_1, gnutls to 2.4.2_1, and tshark-lite to 1.0.5 (before wireshark port was bumped to use libgcrypt-1.4.3).
