No that won't solve it. (libcloog-ppl-dev is already a dependency).

However, it turned out that the problem was with a certain gcc version,
which was looking for libcloog-ppl0, but only libcloog-ppl1 was
available (SONAME bumped). So gcc bailed out with that message. (s.a.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=712257)

But the m4 macro did not detect that, so the test for the safety to use
-floop-parallelize-all is IMHO incomplete as it should actually try to
compile/link a programm using that feature to see if that works.

Title:
  m4/pandora.warnings check for libcloog does not work reliably detect
  availability.

Status in A Lightweight SQL Database for Cloud Infrastructure and Web Applications:
  Incomplete

Bug description:
  During building for Debian I figured out that there are currently some
  ports which have old gccs (4.6.3)* which seems still to look for
  libcloog-ppl0 while only  libcloog-ppl1 is available.

  This triggers some build failures for several architectures as
  configure comes to the conclusion:

  checking whether it is safe to use -floop-parallelize-all... yes

  but later gcc will tell that libcloog is not available:

  plugin/innobase/pars/pars0lex.c: In function 'yy_get_previous_state':
  plugin/innobase/pars/pars0lex.c:2232:26: sorry, unimplemented: Graphite loop optimizations can only be used if the libcloog-ppl0 package is installed
  plugin/innobase/pars/pars0lex.l: In function 'string_append':
  plugin/innobase/pars/pars0lex.l:62:1: sorry, unimplemented: Graphite loop optimizations can only be used if the libcloog-ppl0 package is installed
  plugin/innobase/pars/pars0lex.c:2581: confused by earlier errors, bailing out
  Preprocessed source stored into /tmp/ccLiPdWj.out file, please attach this to your bugreport.
  make[4]: *** [plugin/innobase/pars/plugin_innobase_libpars_la-pars0lex.lo] Error 1
