You ought to give the --prefix when doing the Configure, as the install path is compiled into the binary (because the default @INC is derived from it).

However, I'm not sure what you mean by "Perl5.8.1 is located now at /usr/lib/perl5/5.8.1". Do you mean every file related to Perl, including the binaries? That's an odd setup. But if you mean the libraries/modules, than that's normal. 5.8.1 libraries go into /usr/lib/perl5/5.8.1, 5.8.7 libraries go into /usr/lib/perl5/5.8.7, and perl5.8.7 will still be able to use the libraries from /usr/lib/perl5/5.8.1.
