You've now got something that won't work on anybody else's machine but
yours, because we aren't going to make anybody create that themselves.
My recollection from earlier in this discussion was that cilk built
without doing this, but that when you compiled stuff using cilk you had
a problem. Is this the case?
What we meant by "make a local copy" was to install the modified file
somewhere appropriate within the cilk package:
%i/lib/%n/include/_structs.h
(%i is the install directory). If you _do_ need to use the modified
_structs.h for building cilk itself, then see below.
and we have

That's wrong for several reasons:
1) packages aren't supposed to build against versions of themselves that
are currently installed.
2) Fink doesn't support arbitrary directories within its tree; i.e.
/sw/clkheader shouldn't exist. Since you created this by hand, Fink
didn't detect that this is bad.
If, as mentioned above, you need a modified _structs.h to build cilk,
then you'll want to create that within the cilk build directory and make
sure that the compiler uses that file rather than the system's.

Does cilk have any environment variables that it uses to look for
headers and libraries in nonstandard locations (e.g. analogous to
CPPFLAGS)? If so, then you can set those variables via RuntimeEnvVars.

I can test on PowerPC, but don't email me the file until you have
addressed the questions which I have raised above to my satisfaction,
and I give you the OK to do so.
