If I set GFORTRAN_VERSION=8 and PKGSRC_DEVELOPER=yes, I get the 
following, which I think matches your results:

=> Automatic manual page handling
=> Generating post-install file lists
=> Checking file-check results for cblas-3.9.0
=> Checking for non-existent script interpreters in cblas-3.9.0
=> Checking file permissions in cblas-3.9.0
=> Checking for missing run-time search paths in cblas-3.9.0
ERROR: lib/libcblas.so.3.9.0: missing library: libgfortran.so.5
ERROR: lib/libcblas.so.3.9.0: missing library: libquadmath.so.0
*** Error code 1

I noticed that my CentOS setup also has GCC_REQD explicitly set to the 
same value as GFORTRAN_VERSION.  Based on that, I found that the 
following also alleviates the problem:

I think the problem may be that gcc.mk sets _GCC_REQD before looking at 
Fortran requirements.
