| 
| No, it is a system library function we use. From 'man backtrace_symbol' :
| 
| BACKTRACE(3)                      Linux Programmer's Manual                     BACKTRACE(3)
| 
| NAME
|        backtrace,  backtrace_symbols,  backtrace_symbols_fd  - support for application self-
|        debugging
| 
| SYNOPSIS
|        #include <execinfo.h>
| 
|        int backtrace(void **buffer, int size);
| 
|        char **backtrace_symbols(void *const *buffer, int size);
| 
|        void backtrace_symbols_fd(void *const *buffer, int size, int fd);
| [...]

A quick Google search for 'backtrace_symbols FreeBSD' points to a need for
linking with -lexecinfo

Can you please modify src/Makevars at your end by adding this line right
after the line containing PKG_CPPFLAGS:

PKG_LIB += -lexecinfo
