Created attachment 242942 [details] Fix I've already written to the port maintainer directly but haven't heard back in two month. I'm maintaining my own built of FreeBSD ports and for that I tend to disable a bunch of options here and there to get a learner dependency tree. One of these is unsetting JPEG when building math/R. Doing that makes building graphics/R-cran-jpeg fail: gmake[1]: Entering directory '/wrkdirs/usr/ports/graphics/R-cran-jpeg/work/jpeg/src' cc -I"/usr/local/lib/R/include" -DNDEBUG -DLIBICONV_PLUG -I/usr/local/include -isystem /usr/local/include -fpic -O2 -pipe -DLIBICONV_PLUG -fstack-protector-strong -isystem /usr/local/include -fno-strict-aliasing -c read.c -o read.o In file included from read.c:1: ./rjcommon.h:11:10: fatal error: 'jpeglib.h' file not found #include <jpeglib.h> The reason for this is, that math/R without JPEG will not depend on jpeg-turbo and this it will not be implicitly installed when building CRAN ports. So there'll be no jpeglib.h to be found. On default (meaning JPEG option set for math/R) it'll be there "coincidentally" so everything works. The fix for this is the explicitly USES=jpeg in graphics/R-cran-jpeg. Patch is attached.
