I found the solution by use gcc.
https://lists.freebsd.org/pipermail/freebsd-toolchain/2014-April/001150.html
On install.sh, add
export LD_LIBRARY_PATH=/usr/local/lib/gcc48:$LD_LIBRARY_PATH
export CC=gcc
export CXX=g++
On trepl-scm-1.rockspec, add
unix = {
modules = {
['readline'] = {
sources = {'readline.c'},
libraries = {'readline'},
incdirs = {"/usr/local/include"},
libdirs = {"/usr/local/lib"}
}
}
}
