You don't provide much information about your situation, but I assume that
you talk about Linux here. If you need version 2, you may need to link
explicitly to libfoo.2.so rather just libfoo.so. If you link to libfoo.so
and this is expected to be a symbolic link to the latest installed
version, you may also want to check why people having both libfoo 1.0 and
libfoo 2.0 installed do not have the symbolic link pointing to the later
version. One such reason may be not having the development version of the
respective library installed (at least this may be the case on some Linux
distributions as far as I know).
