I downloaded ActivePerl today and I saw that an 64-bit (AMD64) was

release? Is this due to extensions included in ActiveTcl?

The Tcl sources support being built as 64-bit binaries on many
platforms, and I suspect most of the other packages in the ActiveTcl
should support it straight out of the box too. Whether enough do to
support 64-bit builds for all Unix platforms, I don't know. Windows is
a bit different; there are enough changes there for 64-bit-ness that
some of the extensions (especially ones that provide widgets written
in C/C++) may well not be updated yet. Maybe someone who knows more
about iTk/iWidgets and the Vu widgets can tell us more?

Tcl 8.4.14 (not 8.4.13) and Tk compile on 64-bit FC6 and Centos4.4
as well as Oratcl does.
BLT has a bug in bltTree.c that is quite easy to fix to get
it compiled (definition of START_LOGSIZE and MAX_LIST_VALUES
has to be put in front of the #if (SIZEOF_VOID_P == 8) ).
On Itcl I could not succeed due to errors in the ./configure
script.
Actually, I am stuck with compiling BLT against ActiveTcl8.4.14,
where I get 32/64-Bit conflicts when BLT tries to bind tk:
/usr/bin/ld: skipping incompatible /opt/ActiveTcl-8.4/lib/libtk8.4.so
when searching for -ltk8.4
/usr/bin/ld: skipping incompatible /opt/ActiveTcl-8.4/lib/libtk8.4.a
when searching for -ltk8.4
So, it is actually really a mess and I would appreciate a 64-bit
ActiveTcl-installation too.
