A few more remarks

• hashbang

  clawsker starts with "#!/usr/bin/perl -w", which will horribly fail
  on all systems where "perl"'s $PATH is not /usr/bin, as it it is
  likely not the perl where the required modules are installed.

  Many other parts of clawsker are more or less dynamic and changed by
  the make process (e.g. @PREFIX@)

  $ perl -V:startperl

  might be a start to create a clawsker that runs correct in the users

  I would suggest changing the Makefile:

	sed -e "s, at PREFIX@,${PREFIX},;s, at LIBDIR@,${LIBDIR},;s, at VERSION@,${VERSION},;s, at DATADIR@,${DATADIR}," < ${NAME} > build/${NAME}


	perl -MConfig -p -e'1..1 and s/.*/$$Config{startperl}/;' \
		-e's,\@PREFIX\@,${PREFIX},;' \
		-e's,\@LIBDIR\@,${LIBDIR},;' \
		-e's,\@VERSION\@,${VERSION},;' \
		-e's,\@DATADIR\@,${DATADIR},' ${NAME} > build/${NAME}.2

  and add "use warnings;" below "use strict;" in clawsker itself to
  compensate for the old-fashioned -w


  Again, I don't think /usr/local is a good default. The script itself
  uses the File::Which module to find out, so why not use the same for
  the transistion?

  PREFIX ?= /usr/local


  PREFIX ?= $(shell perl -MFile::Which -E'say which ("claws-mail") =~ s{/[^/]+\z}{}r')


  PREFIX ?= $(shell which claws-mail | perl -pe's{/[^/]+\z}{}')
