Update to 3.2.5 and fix broken build.
pkgsrc changes:
- use paxctl during the build to avoid crashes
- depend directly on pcre
- fix some pkglint

Upstream changes:
- Add Delay>>#value:onTimeoutDo: as an easy way to timeout an operation.
- Improve Delay and millisecondClock behavior across image save and restore.
  millisecondClockValue is guaranteed to be monotonic across image save, and
  delays are restarted when the image is restored.
- DateTime>>#today will return midnight of the current timezone.
- DateTime has a new method #asLocal.
- DateTime>>#readFrom: can read more time formats.
- Time resolution is now based on nanoseconds.
- Absolute-time delays (Delay>>#untilMilliseconds:) are precise and not
  anymore converted to relative-time delays.
- package.xml files support a <dir> tag, like <dir name="Foo">.  It can
  be used to make package.xml clearer for large packages.
- MethodDictionary is now thread-safe.
- String>>#% supports string keys, like %(string).  They can be used
  when the argument of #% is a Dictionary or LookupTable.  Note that
  the keys of the dictionary must be Strings, not Symbols.
- Socket fixes including reporting of EndOfStream on broken pipes and
  connection resets.
- Fix the FileDescriptor finalization code to close open descriptors.
- The system file descriptor of FileDescriptor is set to nil on image
  restore.
- The asynchronous event notification has been rewritten.  The old
  version could fail when many file descriptors became available at
  the same time.
- DBD-Postgres gained support to bind parameters on queries and various
  fixes to allow to resume images that use Postgres.
- Images created with gst-remote can now be resumed.
- Add #system:withArguments: to avoid using #system: with #% to add
  arguments.
- Added Integer>>#printPaddedWith:to:.
- Added CharacterArray>>#withShellEscapes
- Added Collection>>#includesAllOf:
- Stream>>#fold: works correctly.
- 64-bit integer types are available using CLongLong and CULongLong.
- gst-blox and gst-browser understand the -i/--rebuild-image option.
- GObject errors show backtraces.
- Improvements to multiarch support.
- CType objects implement #= and #hash, so they can now be used as keys
  in a dictionary.
- Floating-point numbers are printed more accurately in some rare cases.
- Some optimization of OrderedCollection and SortedCollection
- Selectors starting with an underscore are treated as keyword messages.
- A new function gst_uint_to_oop is in libgst, and uintToOOP is also
  provided by the VMProxy.
- Growing the heap is working again.
- Various bugfixes.
- GNU Smalltalk does not run anymore on i386 hardware, an i486 is needed.
- Slightly faster garbage collection.
