It's probably because Makefile.inc1 contains:
.if ${MK_CASPER} != "no"
_lib_casper= lib/libcasper
.endif
so WITHOUT_CASPER means that the libcasper dir isn't even visited when
prebuilding libs. But you need to visit that dir so that it can
install the header file (but not the lib, because MK_CASPER will be
"no"). I think lib/libcasper just needs to be unconditionally listed
as one of the prebuild libs in Makefile.inc1.
