rpmdeps uses, according to ldd:

        linux-vdso.so.1
        librpm-5.4.so
        librpmdb-5.4.so
        librpmio-5.4.so
        librpmmisc-5.4.so
        libm.so.6
        libdl.so.2
        libacl.so.1
        libattr.so.1
        libpcreposix.so.0
        libdb-5.1.so
        libmagic.so.1
        liblzma.so.5
        libbz2.so.0
        libz.so.1
        libpthread.so.0
        librt.so.1
        libelf.so.1
        libpopt.so.0
        libssl.so.0.9.8
        libcrypto.so.0.9.8
        libpcre.so.0
        libc.so.6
        libgcc_s.so.1
        /lib64/ld-linux-x86-64.so.2 (0x0000003c51800000)

The issue is that it uses the librpm, librpmdb, librpmio, and librpmmisc
libraries.  These libraries provide and use all of the rest of the components.

pcre is used to handle the file lists and any patterns to generate the lists, or
dependent informtion.  So that is needed.  expat may be needed in the future, I
don't see that it is today.
