[plt-scheme] looking for libc.so.6

Hello,

How can I run plt/install and tell it where to find libc?

I'm trying to install mzscheme onto a machine where
I don't have root privileges (hosted by my ISP).

I've unpacked and installed the tarfile but I can't
run ./install because it can't locate libc.so.6.
I tried linking libc.so.6 to the plt directory.
I've even tried adding it into $LD_LIBRARY_PATH.

hauda.pair.com> locate libc.so.6
/usr/compat/linux/lib/libc.so.6
hauda.pair.com> echo $LD_LIBRARY_PATH
/usr/compat/linux/lib
hauda.pair.com> pwd
/usr/home/straz/lib/plt
hauda.pair.com> ls -l libc*
lrwxr-xr-x  1 straz  users  31 Jul 29 18:05 libc.so.6@ ->
/usr/compat/linux/lib/libc.so.6
hauda.pair.com> ./install
./bin/mzscheme: /lib/libc.so.6: version `GLIBC_2.2.4' not found
(required by ./bin/mzscheme)
./bin/mzscheme: /lib/libc.so.6: version `GLIBC_2.2' not found (required

./bin/mzscheme: /lib/libc.so.6: version `GLIBC_2.1.3' not found

thank you
