compile error - src/send_bw.c:179:30: error: ‘VERSION’ undeclared

[BaobabAfter17]

Hi dear developers,

I am installing perftest on my machine and got the following error:

/path/to/perftest$ make
make  all-am
make[1]: Entering directory '/path/to/perftest'
  CC       src/send_bw.o
src/send_bw.c: In function ‘main’:
src/send_bw.c:179:30: error: ‘VERSION’ undeclared (first use in this function); did you mean ‘DURATION’?
  strncpy(user_param.version, VERSION, sizeof(user_param.version));
                              ^~~~~~~
                              DURATION
src/send_bw.c:179:30: note: each undeclared identifier is reported only once for each function it appears in
make[1]: *** [Makefile:950: src/send_bw.o] Error 1
make[1]: Leaving directory '/path/to/perftest'

did not see any error when ./autogen.sh and ./configure, except:

./configure: line 14528: test: =: unary operator expected
