NURBS package: 'nrbeval' crashes when calling 'bspeval'

Subject: NURBS package: 'nrbeval' crashes when calling 'bspeval'
Date: Wed, 24 Apr 2013 07:56:59 -0700 (PDT)

After having successfully installed and loaded the NURBS package (see  here
<http://octave.1599824.n4.nabble.com/At-least-apparently-unable-to-install-packages-tp4652176.html>
 
), its fundamental command /nrbeval/ (points of a NURBS from parametric
values) crashes when it calls /bspeval/: 

/error: nrbeval:
/usr/lib/x86_64-linux-gnu/octave/packages/nurbs-1.3.6/x86_64-pc-linux-gnu-api-v48+/bspeval.oct:
failed to load:
/usr/lib/x86_64-linux-gnu/octave/packages/nurbs-1.3.6/x86_64-pc-linux-gnu-api-v48+/bspeval.oct:
undefined symbol: GOMP_parallel_start
error: called from:
error:   /usr/share/octave/packages/nurbs-1.3.6/nrbeval.m at line 233,
column 7/

This is row 233 of nrbeval.m:

/val = bspeval(nurbs.order-1,nurbs.coefs,nurbs.knots,tt);/

Why does it fail to work?

Thanks in advance.
