Compile Guile check has failures

I downloaded Guile tarball release from here.

I installed required libraries mentioned in the README file:

sudo apt-get install \
  libgmp-dev \
  libc6-dev \  # contains libiconv according to http://ift.tt/2q41teA
  libint1 \
  libltdl-dev \
  libunistring-dev \
  libgc-dev \
  libffi-dev \
  libreadline-dev

Then I followed the instructions here:

./configure --prefix=/usr    \
            --disable-static \
            --docdir=/usr/share/doc/guile-2.2.2 &&
make      &&
make html &&

makeinfo --plaintext -o doc/r5rs/r5rs.txt doc/r5rs/r5rs.texi &&
makeinfo --plaintext -o doc/ref/guile.txt doc/ref/guile.texi

To build it. Then I did the check thing:

./check-guile

Unfortunately there are failures. Now I do not know, whether my Guile would work fine, or if I should rebuild with any other things installed that it needs to pass all tests. (Is it supposed to pass all tests?)

Will my Guile be working fine, if the following is the log of ./check-guile &> log_file?:

The number of passed tests and unresolved test cases slightly varies when I run the check again. I assume that has to do with some pseudo randomness in test cases.
