i am assuming that the distfiles on the cdrom preserve the same structure as on the ftp sites and also created during builds.
to illustrate: $ env CDROM_SITE=/home/olddistfiles DISTDIR=/home/distfiles make fetch ===> Checking files for bash-4.3.42 cp: /home/olddistfiles/bash-4.3.30.tar.gz: No such file or directory >> Fetch http://ftpmirror.gnu.org/bash/bash-4.3.30.tar.gz bash-4.3.30.tar.gz 100% |*******************************| 7790 KB 00:10 cp: /home/olddistfiles/bash43-031: No such file or directory >> Fetch http://ftpmirror.gnu.org/bash/bash-4.3-patches/bash43-031 bash43-031 100% |*************************************| 3689 00:00 ... i modified the makefile to echo what it is doing: $ env CDROM_SITE=/home/olddistfiles DISTDIR=/home/distfiles make fetch ===> Checking files for bash-4.3.42 cd /home/distfiles/bash test -f bash-4.3.30.tar.gz && exit 0 if cp -f /home/olddistfiles/bash-4.3.30.tar.gz .; then exit 0; fi cp: /home/olddistfiles/bash-4.3.30.tar.gz: No such file or directory >> Fetch http://ftpmirror.gnu.org/bash/bash-4.3.30.tar.gz bash-4.3.30.tar.gz 100% |*******************************| 7790 KB 00:14 cd /home/distfiles/bash test -f bash43-031 && exit 0 if cp -f /home/olddistfiles/bash43-031 .; then exit 0; fi cp: /home/olddistfiles/bash43-031: No such file or directory >> Fetch http://ftpmirror.gnu.org/bash/bash-4.3-patches/bash43-031 bash43-031 100% |*************************************| 3689 00:00 when checking for existing files, it changes to the directory the files should be in ie FULLDISTDIR, $DISTDIR/bash in the above case. if CDROM_SITE used, then the code below is run . if defined(FETCH_SYMLINK_DISTFILES) _CDROM_OVERRIDE = if ln -s ${CDROM_SITE}/$$f .; then exit 0; fi . else _CDROM_OVERRIDE = if cp -f ${CDROM_SITE}/$$f .; then exit 0; fi . endif via f=$f; \ ${_CDROM_OVERRIDE}; \ the problem is that the file it tries to copy or link to is the filename in DISTDIR, not FULLDISTDIR. so in the case of bash, it tries 'cp -f ${CDROM_SITE}/bash-4.3.30.tar.gz' instead of 'cp -f ${CDROM_SITE}/bash/bash-4.3.30.tar.gz' the fix is trivial: --- infrastructure/mk/bsd.port.mk.orig Thu Jan 7 04:25:02 2016 +++ infrastructure/mk/bsd.port.mk Mon Feb 8 12:37:24 2016 @@ -2960,7 +2960,7 @@ ${DISTDIR}/$p: @lock=${@:T}.dist; ${_SIMPLE_LOCK}; install -d ${DISTDIR_MODE} ${@:H}; \ cd ${@:H}; \ test -f ${@:T} && exit 0; \ - f=$f; \ + f=$p; \ ${_CDROM_OVERRIDE}; \ for site in ${$m}; do \ file=$@.part; \ run again with the above change, and echo statements: $ env DISTDIR=/home/distfiles CDROM_SITE=/home/olddistfiles make fetch ===> Checking files for bash-4.3.42 cd /home/distfiles/bash test -f bash-4.3.30.tar.gz && exit 0 if cp -f /home/olddistfiles/bash/bash-4.3.30.tar.gz .; then exit 0; fi cd /home/distfiles/bash test -f bash43-031 && exit 0 if cp -f /home/olddistfiles/bash/bash43-031 .; then exit 0; fi
