I haven't finished writing them :-). By being forced to fork opendkim and
manage my own version controlled repository I've got it to a pretty portable
state with an audible trail of changes and history. I couldn't of achieved
this using CVS.

the simple act of doing
PKG_CHECK_MODULES([LIBCRYPTO]
PKG_CHECK_MODULES([LIBTRE]

provides an equivalent in the environment. from ./confiugre --help:
  LIBCRYPTO_CFLAGS
              C compiler flags for LIBCRYPTO, overriding pkg-config
  LIBCRYPTO_LIBS
              linker flags for LIBCRYPTO, overriding pkg-config
  LIBTRE_CFLAGS
              C compiler flags for LIBTRE, overriding pkg-config
  LIBTRE_LIBS linker flags for LIBTRE, overriding pkg-config

So setting the _LIBS to -L /usr/to/lib -llib and _CFLAGS to -I
/usr/to/include/file generates the equivalent without a compile time
dependency on pkg-config.

from the info and testing I did I couldn't see an error. I'm happy to help
diagnose this though.
