1. Run file on one of the binary files it installed, and see whether it
says "32-bit" or "64-bit".
Trivial example (using /bin/cat, which is installed everywhere):
64_bit_box $ file /bin/cat
/bin/cat: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux
2.6.8, dynamically linked (uses shared libs), stripped
32_bit_box $ file /bin/cat
/bin/cat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.2.0, dynamically linked (uses shared libs), stripped
2. Run ldd on one of the binary files it installed, and count the hex digits.
64_bit_box $ ldd /bin/cat
linux-vdso.so.1 => (0x00007fff357fe000)
libc.so.6 => /lib/libc.so.6 (0x00002acd75500000)
32_bit_box $ ldd /bin/cat
libc.so.6 => /lib/libc.so.6 (0x4001c000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
On the 64-bit box we see 16 digits. On the 32-bit box, only 8 digits. If you
get a "not found" anywhere, that could well be your problem.
If you haven't actually installed it, run ar -x on the .deb file, unpack the
data.tar.gz that gets created, and look in the "bin" folder that gets created
for the files in question.
