I found links about ucred.h and user credentials, but I don't know how to apply
this information in my system.
http://docs.huihoo.com/darwin/kernel-programming-guide/security/chapter_3_section_4.html
http://manpages.ubuntu.com/manpages/jaunty/man9/crdup.9freebsd.html
I downloaded the ucred.h and I got teh same erros too...
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/head/ucred.h?a=true
I tried (just a test) to install a cpan module, but got this error:
cpan[1]> install Sun::Solaris::Ucred
Checking if your kit is complete...
Looks good
