It is the posix_spawn on line 102 of libpkg/script.c. The argument length is limited to KERN_ARGMAX (sysctl kern.argmax) which seems to be a R/O value initialized to 256KB. AFAICT this is not even a loader tuneable. A new kernel must be built, or pkg must be modified to honor the argument length limit. The argument is the string argument of "sh -c <string>", which can not be split in the general case. In the specific case of math/lapack, the arguments to execve() (called by posix_spawn()) are: argv[0] = "sh" argv[1] = "-c" argv[2] = " set -- lapack-3.4.0_2 rm -f /usr/local/man/cat3/INSTALL_ilaver.f.3.gz ... /usr/local/man/cat3/zupmtr.f.3.gz.bz2" The argument list must be broken into pieces of less than 256KB, since rising KERN_ARGMAX to >330KB will lead to the same problem with the next port with even longer PLIST.
