EV on AIX?

[Darin McBride]

I'm playing with perl 5.15.9 on AIX 64-bit, and thought I'd try installing EV 
with Coro.  However, I get the following error:

$ make
        cc -q64 -c  -Ilibev  -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -

I'm imagining here, then, that AIX is not supported (yet?).  If it's merely 
that I've set something up incorrectly, I'd be interested to know what I could 
do to get this installed.  Worst case scenario is the fallback to AE's pure-
perl loop.
