>Description:

For about 2/3 days now, I've noticed that whenever I compile *any* pkgsrc 
package, I'm getting errors saying, for example:

/usr/bsd/var/tmp/graphics/tiff/work/.wrapper/bin/cc[50]: : cannot execute

Now "/usr/bsd/var/tmp/graphics/tiff/work/.wrapper/bin/cc" definitely exists, 
and is definitely executable - so is "[50]" or even "[50]: " accidentally being 
appended to the path to $CC?

I'm using the MIPSpro compilers ("PKGSRC_COMPILER=mipspro" in mk.conf and 
--preserve-path passed to the bootstrap script), so I don't know if this 
problem turns up in the general case.

Also note that I haven't actually experienced any build failures since this 
problem began to occur - so a compiler is definitely being found somewhere!

(I'm wondering if this is a linker thing... a sample chunk of output from 
building libtiff is:

... etc.  So the "cannot execute" warning seems to come after compiling the 
code, but before linking it)
