Did I mention that I like rsnapshot very much? Well, I do, but this particular installation is giving me the heebeegeebees:

  WARNING: Could not lchown() symlink "/foo/some/symlink"

Apparently my Perl installation does not have the Lchown module, hence the messages. Well, I switched from SunFreeware to OpenCSW, but rsnapshot is using /usr/bin/perl anyway and rsnapshot itself is from a current GIT checkout, so why are these messages coming up just now? The cure for this is to install Lchown from CPAN - unfortunately, this does not went so well, and we have a lot of CPAN surgery ahead just to get Lchown working (again?):

  CPAN.pm: Going to build N/NC/NCLEATON/Lchown-1.00.tar.gz

sh: cc: not found
*** Error code 1

Well, we could edit Config.pm, but this stock Perl-5.8 installation from Solaris10 does not seem to have this file. The OpenCSW version was no better, forcing it to compile with gcc did not succeed either, as expected:

[...]
gcc -c   -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -xarch=v8 -D_TS_ERRNO \
           -xO3 -xspace -xildoff    -DVERSION=\"1.00\"  -DXS_VERSION=\"1.00\" -KPIC \
           "-I/usr/perl5/5.8.4/lib/sun4-solaris-64int/CORE"   Lchown.c
gcc: unrecognized option `-KPIC'
gcc: language ildoff not recognized
gcc: Lchown.c: linker input file unused because linking not done

So I went a different direction:

$ wget http://rsnapshot.org/downloads/extras/Lchown-1.00.tar.gz -O - | gzip -dc | tar -xf -
$ cd Lchown-1.00
$ perl Makefile.PL

Running rsnapshot again, the errors are gone now, heh!
