32/64-Bit Library Confusion

Good morning,
I'm on CentOS 6.2_x86-64 on a Dell PE 1900 using Intel Xeon 5130 processors and I recently got gcc-4.7.0 built and installed, along with all the requirements and dependencies, separate from the system installed versions.? It all appears to be working, but, I'm having a bit of confusion over libstdc++ and the 32/64-bit version.
I've got:
ultra-trix:~/toolchain 09:44:32
73_ file lib/libstdc++.so.6.0.17
lib/libstdc++.so.6.0.17: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
ultra-trix:~/toolchain 09:44:47
74_ file lib64/libstdc++.so.6.0.17
lib64/libstdc++.so.6.0.17: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped
ultra-trix:~/toolchain 09:44:54
75_
but when I try and build C++ libraries like PPL (or my own libraries), I get the follow:
/export/home/ultra-trix/brian/toolchain/lib/../lib/libstdc++.so: could not read symbols: File in wrong format
collect2: error: ld returned 1 exit status
make[3]: *** [libppl.la] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
ultra-trix:~/toolchain/src/ppl-0.12/x86_64 09:49:02
77_
This came from trying to build and link PPL.? My environment looks like the following:
78_ echo $PATH
/export/home/ultra-trix/brian/x86_64:/export/home/ultra-trix/brian/x86_64/script:/export/home/ultra-trix/brian/toolchain/bin:/usr/local/bin:/usr/local/gnu/bin:/export/home/ultra-trix/brian/mvp/work/pcb-X64/brian-pcb/bin:/usr/bin:/bin:/opt/pdk/bin:/opt/ActivePerl-5.10/bin:/opt/ActivePerl-5.10/site/bin:/usr/bin/X11:/sbin:/usr/sbin:/spare1/XDesigner-7.0/bin:/usr/etc:/opt/mvp/pbm
ultra-trix:~/toolchain/src/ppl-0.12/x86_64 09:49:45
79_ echo $LD_LIBRARY_PATH
/export/home/ultra-trix/brian/toolchain/lib64:/export/home/ultra-trix/brian/toolchain/lib:/export/home/ultra-trix/brian/mvp/work/pcb-X64/lib:/export/home/ultra-trix/brian/mvp/work/pcb-X64/brian-pcb/lib:/usr/lib:/lib:/usr/local/lib:/usr/local/gnu/lib:/spare1/XDesigner-7.0/lib/X11
ultra-trix:~/toolchain/src/ppl-0.12/x86_64 09:49:50
80_
And I've configured PPL as follows:
? $ ../configure --prefix=/export/home/ultra-trix/brian/toolchain --enable-share
d --enable-static --with-gmp=/export/home/ultra-trix/brian/toolchain
I'm not sure what I'm missing here, but clearly, I'm doing something wrong.? Someone please point me in the right direction?
Thanks,
-brian
