[gentoo-alt] revdep-rebuild and install_name

[Johan Hattne]

Dear all;

It would seem revdep-rebuild broke on macos after the upgrade to  
gentoolkit-0.2.4.  Attached patch addresses this, I believe.  With  
this patch applied, revdep-rebuild suddenly wanted to re-emerge some  
unexpected stuff.  Turns out that those were all cases where  
libraries were linked with a funny -install_name, or, in the case of  
ncurses, the libraries were moved from were src_compile() intended  
them to be.

So if this is real, and something to worry about (wrongly set install  
names don't seem to break anything in prefix, as long as the linker  
can still find what it's looking for) I have small patches for  
ghostscript-esp-8.15.4, jbigkit-1.6-r1, libperl-5.8.8-r1, ncurses-5.5- 
r03.1 and readline-5.2_p4 as well.

// Cheers; Johan
