When installing Evolution after compiling successfully (on Solaris 9 with
forte), happened error as follows:

Libtool has attempted to create the file .libs/libeconduit.a. But because
there's no any library input, it wasn't created finally.

Search in Makfile, found:

    libeconduit_la_LDFLAGS =
    libeconduit_la_LIBADD =
    libeconduit_la_OBJECTS =
    ......
    libeconduit.la: $(libeconduit_la_OBJECTS) $(libeconduit_la_DEPENDENCIES)
            $(LINK) -rpath $(privlibdir) $(libeconduit_la_LDFLAGS)
$(libeconduit_la_OBJECTS) $(libeconduit_la_LIBADD) $(LIBS)

Read more in Makefile.in, found:

    libeconduit_la_LDFLAGS =
    libeconduit_la_LIBADD =
    @ENABLE_PILOT_CONDUITS_FALSE@libeconduit_la_OBJECTS =
    @ENABLE_PILOT_CONDUITS_TRUE@libeconduit_la_OBJECTS =  e-pilot-map.lo \
    @ENABLE_PILOT_CONDUITS_TRUE@e-pilot-settings.lo e-pilot-util.lo

OK, we can know why the file .libs/libeconduit.a doesn't exist.

Since pilot-conduits is a option, I think it must be check when installing.
Otherwise, if we build basic evolution without pilot-conduit option, must
will meet this install error.

I think it is Solaris specially.

On Linux, with the same command ar cru libeconduit.a, the object file was
created. Although the file only include !<arch> as its content.
