I have ports installed under /usr/ports and even the new version fails
with the same error as before:

> make makesum
> make install

Now it start to configure and compile libgcrypt-1.4.5_1 but it's
installed already due to gnutls and curl. In the end it fails:

...
===>  Installing for libgcrypt-1.4.5_1
===>   Generating temporary packing list
===>  Checking if security/libgcrypt already installed
===>   libgcrypt-1.4.5_1 is already installed
      You may wish to ``make deinstall'' and install this port again
      by ``make reinstall'' to upgrade it properly.
      If you really wish to overwrite the old port of security/libgcrypt
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.
*** Error code 1
Stop in /usr/ports/security/libgcrypt.
*** Error code 1
Stop in /usr/src/foobar/jason/libvirt.

When I try to resolve that as suggested and try to run make for
libvirt again it fails with a version mismatch as it seems:

freebsd# make
===>   libvirt-0.9.1 depends on file: /usr/local/bin/python2.6 - found
===>   libvirt-0.9.1 depends on executable: gmake - found

===>   Returning to build of libvirt-0.9.1
Error: shared library "gcrypt.17" does not exist
*** Error code 1
Stop in /usr/src/foobar/jason/libvirt.

Maybe my ports tree is outdated? I installed this FreeBSD 8.1 virtual
machine like half a year ago and didn't update it since then.
