x86_64 is 64-bit but it is not a powerpc architecture.
your info below indicates that you have a 64-bit powerpc
which means that you need a different tcl library.

in general, there are multiple components that define binary
compatibility. the processor architecture (and that is defined
by architecture and bitness, and endianness) , the operating
system and the compiler/c-library ABI.

64-bit and linux is not sufficiently accurate.
