I'm unable so far to get xpdf-tools to build statically on the mac. These are the changes to get it to build on the Mac in an attempt to make static xpdf-tools binaries. Running otool minus L on the binaries however shows that they're linking to dylib dlls, albeit our ones for freetype, libpng and zlib.

227# Note that PNG_LIBRARIES includes zlib/lz: "-lpng -lz", and along with freetype,
228# these are linked statically. However, Threads/lpthread is included as a dynamically
229# linked library instead of including a .a (regardless of whether it's appended
230# as -lpthread or Threads::Threads in else above), contributing to the pdfhtml binary
231# produced being a partially static, partially dynamic one,
232# so a dynamic executable overall.
233# The order of dynamic .so files listed by ldd in the broken binary differs from
234# a manually linked working version of pdftohtml, and seems to be the only difference
235# between the two in ldd output. Not using "-Wl,-Bstatic" and using -static (-Bstatic on Mac)
236# in its place creates a partially static dynamic executable that isn't broken, whereas
237# additionally removing "-Wl,-Bdynamic -lpthread" and replacing it with -lpthread
238# moreover produces a working pdftohtml that is a fully static linked executable.
239# The inclusion of the math lib and c lib (lm and lc) in the final link command
240# are to completely bypass the remaining .so dependencies that were present in
241# the executable and produce the fully static executable.
242# Not sure what colormanager (lcms) and typelibrary, or how they're written in -l
243# form as they were not present when the original unmodified static linking command
244# was run, so they've not been included in the replacement static linking command.
