I fixed this in tree basically with your fix below. Basically these checks should always be done, not just in certain conditions. The problem with this is they have error messages right in the tags, so it will take a bit of rework that is probably not worth it.

After some digging it looks to me like a dependency problem in the libjs autoconfig setup. The patch below works around the issue but there's likely a better way.

> It appears that using AC_CHECK_HEADER at 'autoconf' time remembers that the check for, say, EGREP has been done and prevents it from being issued again in the resulting configure script, however if AC_CHECK_HEADER is used in a runtime 'if' block (the 'if' runs when configure runs, not autoconf) and that if does not pay off AC_PROG_LIBTOOL ends up w/o EGREP defined and the check if we can build a shared library fails (and thus no .so is built).
> A simple workaround is to move AC_PROG_LIBTOOL up above the AC_ARG_WITH([dso ... check which uses AC_CHECK_HEADER in a bash if block (which does not pay off on linux). I'm no autoconf wizard and my lame attempts to force it to check for EGREP again failed -- it may be you're just not supposed to use some things inside an 'if' block at 'configure' time.
