No such file or directory but library exists?

I'm been working on this issue for some time now, and I hope someone can point out what I'm missing.

$ make clean && make libvpnpp.a
c++ -arch x86_64 -arch i386 -I. -I/usr/local/include/ -c VpnInit.cpp
libtool -static -o libvpnpp.a VpnInit.o
libvpnpp.a
make: libvpnpp.a: No such file or directory
make: *** [libvpnpp.a] Error 1

However, when I perform an ls, the library is there:

$ ls *.a
libvpnpp.a

And it is multiarch:

$ lipo -info libvpnpp.a 
Architectures in the fat file: libvpnpp.a are: x86_64 i386

Here are the makefile rules and recipes that are relevant:

IS_DARWIN = $(shell uname -s | $(EGREP) -i -c "Darwin")
ifeq ($(IS_DARWIN),1)
    CXXFLAGS += -arch x86_64 -arch i386
    AR = libtool
    ARFLAGS = -static -o
endif
...

libvpnpp.a: $(VPNPP_LIB_OBJS)
    $(AR) $(ARFLAGS) $@ $(VPNPP_LIB_OBJS)
    $(RANLIB) $@
...

%.o : %.cpp
    $(CXX) $(CXXFLAGS) -I$(VPNPP_INCL) -I$(CRYPTOPP_INCL) -c $<

Why does make fail with No such file or directory even though the library is created and exists?

Here's the tail from make -d:

...
c++ -arch x86_64 -arch i386 -I. -I/usr/local/include/ -c VpnInit.cpp

This looks like $(RANLIB) is empty and then the line $(RANLIB) $@ resolves to just libvpnpp.a. As the first word on a line, the shell wants to execute a program named libvpnpp.a which it doesn't find (probably because . is not in PATH).

Try setting RANLIB=: in the makefile or as a make variable. Or investigate why RANLIB isn't set properly.
