Comment:

 The error is:

 I often use a similar configure line and I can confirm that openjpeg-1.5.1
 does contain this symbol here:
 {{{
 $ nm ../openjpeg-1.5.1/libopenjpeg/.libs/libopenjpeg.so.1.5.0 |grep
 opj_version
 00000000000118c0 T opj_version
 $ nm ../openjpeg-1.5.1/libopenjpeg/.libs/libopenjpeg.a |grep opj_version
 0000000000000000 T opj_version
 }}}
 Either your library was miscompiled or your toolchain has a problem
 afaict.
