Problems compiling NSPR on dreamhost

I am trying compiling NSPR on a Dreamhost host with this result:

/usr/bin/ld: skipping incompatible /usr/bin/../lib/libc.so when searching
for -lc
/usr/bin/ld: skipping incompatible /usr/bin/../lib/libc.a when searching for
-lc
/usr/bin/ld: skipping incompatible /usr/lib/libc.so when searching for -lc
/usr/bin/ld: skipping incompatible /usr/lib/libc.a when searching for -lc
/usr/bin/ld: cannot find -lc
collect2: ld returned 1 exit status 

They said that it is not their problem but I don't think so.
However I can compile other things normally, but I don't do it as root (I am
not allowed).


It is important to me to know the community opinion, so What could be the
reason?
