Here, Solaris 2.5.1 appears to have getrusage. (try 'man
getrusage' on your Solaris box.)
 
When compiling a reasonably current snapshot with gcc, I see:

[blah blah scheduler.cc]
mem-trace.h: In method `void MemInfo::checkpoint()':
In file included from scheduler.cc:49:
mem-trace.h:67: warning: implicit declaration of function `int
getrusage(...)'
[blah blah object.cc etc.]

Lots of stuff on getrusage and Solaris in the list archives; at the
time I wanted ns to run on Solaris 2.4 and 2.5.1 machines, which meant
compiling on 2.4 to run on both.
