Comment (by ctreleaven):

 I think pkg-config is causing this problem.  When it checks for either
 libsamplerate or libsndfile, it returns an include path that we don't
 want:

 {{{
 $ pkg-config --cflags-only-I samplerate
 -I/opt/local/include
 }}}

 Based on help from the pkg-config mailing list, setting an environment
 variable can fix this, ala:

 {{{
 $ PKG_CONFIG_SYSTEM_INCLUDE_PATH=/opt/local/include pkg-config --cflags-
 only-I samplerate

 }}}

 I have the same issue with my mythtv ports and use:

 {{{
 # make pkg-config act like on Linux, no '-I/opt/local/include' in cflags
 configure.env-append    PKG_CONFIG_SYSTEM_INCLUDE_PATH=${prefix}/include
 }}}

 I haven't actually tested building jack with this change, however. HTH.
