Don't enable Aqua support at all on Darwin, it installs X11 headers
which are incompatible with Xquartz, breaking various packages.

Bump PKGREVISION.
Updated x11/tk to 8.6.1nb2
Weak aliases are unsupported on Darwin, so don't do it.  Fixes lots of
dependencies.

Bump PKGREVISION.
Updated lang/g95 to 0.93nb5
Pass --disable-openmp on Darwin.  With changes to g95 and tk, this package
finally builds.
Changes 3.5.0:
* Support for Python 3.3
* Simpler, faster and up-to-date with latest Python code for creating/maintaining interpreter and thread state.
* A much faster WSGI implementation (start_response now implemented in C)
Changes with Apache 2.2.26

  *) mod_dav: dav_resource->uri treated as unencoded. This was an
     unnecessary ABI changed introduced in 2.2.25.

  *) mod_dav: Do not validate locks against parent collection of COPY
     source URI.

  *) mod_ssl: Check SNI hostname against Host header case-insensitively.

  *) mod_ssl: enable support for ECC keys and ECDH ciphers.  Tested against
     OpenSSL 1.0.0b3.

  *) mod_ssl: Change default for SSLCompression to off, as compression
     causes security issues in most setups. (The so called "CRIME" attack).

  *) mod_ssl: Fix compilation error when OpenSSL does not contain
     support for SSLv2. Problem was introduced in 2.2.25.

  *) mod_dav: Fix double encoding of URIs in XML and Location header (caused
     by unintential ABI change in 2.2.25).
Updated www/ap2-python to 3.5.0; www/apache22 to 2.2.26
