Log message:
Changes 8.6.2:
This is a bug-fix release.

Log message:
Set USE_GCC_RUNTIME=yes for packages which build shared libraries but do
not use libtool to do so.  This is required to correctly depend upon a
gcc runtime package (e.g. gcc47-libs) when using USE_PKGSRC_GCC_RUNTIME.

Log message:
Bump PKGREVISION for pulling in zlib dependency, because builds on systems
with PREFER_PKGSRC=yes may have successfully built and installed previously,
but are quite likely broken.

Log message:
The TCL library links with libz, so pull in the dependency.
