I'm trying to get my perl working as I want and when i try to install the module above it fails...

After checking the readme i saw this explanation:
During the 'make test' test.pl will use statvfs()
to stat the root directory "/". If it fails it will
report an error, otherwise it will report all the
standard fields in the statvfs structure.

Does AIX support the statvfs system call? And if so has anyone got this module installed in AIX 5.2 by chance?
