Что не так с этой установкой модуля Net :: SSH2 Perl?

Я пытаюсь установить модуль Net: SSH2 Perl, но выхожу с такой ошибкой:

The libssh2 library is required by this module.  If you don't have it, you can
download it from http://www.libssh2.org; you may also need OpenSSL, which can be
obtained from http://www.openssl.org.

Debian:   sudo aptitude install libssh2-1-dev
OpenSUSE: sudo zypper in libssh2-1 libssh2-devel

You can pass your libssh2 lib and include dirs on the command line. E.g.:

    perl Makefile.PL lib=$HOME/libssh2/lib inc=$HOME/libssh2/include

If you want to build on Windows, see the file BUILDING.WIN32 in the
distribution.

Похоже, я не могу что-то скомпилировать из-за статической компоновки glibc. Однако я не знаю, какая альтернатива glibc-static в CentOS 5.
