The error is the following.

Reading this line, do you use `minimal-uclibc` as the distribution?
There might be a difference in the uClibc or Perl versions used.

I forgot to mention that I have the following in my `local.conf`.

        PREFERRED_UCLIBC_VERSION        = "git"

What does the following command return on your system?

        $ find /oe/build-minimal-uclibc/ -name *libnsl*
        /oe/build-minimal-uclibc/minimal-uclibc-dev/sysroots/armv7a-oe-linux-uclibceabi/lib/libnsl.so.0
        /oe/build-minimal-uclibc/minimal-uclibc-dev/sysroots/armv7a-oe-linux-uclibceabi/lib/libnsl-0.9.32-git.so
        /oe/build-minimal-uclibc/minimal-uclibc-dev/sysroots/armv7a-oe-linux-uclibceabi/usr/lib/libnsl.so
        /oe/build-minimal-uclibc/minimal-uclibc-dev/sysroots/armv7a-oe-linux-uclibceabi/usr/lib/libnsl.a

Searching the WWW I found the following section in the document listing
differences between Glibc and uClibc [1]. 

        8) libnsl provides support for Network Information Service (NIS) which was
        originally called "Yellow Pages" or "YP", which is an extension of RPC invented
        by Sun to share Unix password files over the network.  I personally think NIS
        is an evil abomination and should not be used.  These days, using ldap is much
        more effective mechanism for doing the same thing.  uClibc provides a stub
        libnsl, but has no actual support for Network Information Service (NIS).
        We therefore, also do not provide any of the headers files provided by glibc
        under /usr/include/rpcsvc.

So `libnsl` should be somewhere.

Well let us see whether a newer uClibc helps too. ;-)


Thanks and sorry for leaving out that piece of information,

Paul
