 Something mangling the dependencies hits a bug/feature in Solaris sed 
 (or is it pkgsrc's gsed? or echo/gecho?) that shortens libXpm to libXp? 
 And this piece of code seems to be used only in the toolchain wrapper 
 phase, but not when the actual dependencies are resolved or recorded 
 while installing the package. Here is more context from the build:

 OTOH: trussing the build process shows, that in both cases (i.e. with 
 the line in Makefile intact and commented out) only /usr/gnu/bin/sed is 
 ever executed, no other sed is used. And this happens way before the 
 build process fails. And "echo" is never executed before the build 
 breaks. Okay, now I am puzzled...
