 There's no more to see:
 
 => Replacing sh interpreter in configure.
 warning: unknown switch '--without-openmp' (see ./configure --help for 
 the list)
 
 ld: fatal: bad section layout: .SUNW_ldynsym must precede and be 
 adjacent to .dynsym

 The problem is this code from the configure script:
 
 if ! echo "int main(){}" | "$CC" -xc -std=c99 -o /tmp/gcccheck - > 
 /dev/null; then
 
 Compiling from a pipe does not seem to work:
 
 $ echo "int main(){}" | gcc -xc -o /tmp/gcccheck -
 ld: fatal: bad section layout: .SUNW_ldynsym must precede and be 
 adjacent to .dynsym
 
 And it is indeed the linker:
 
 $ echo "int main(){}" | gcc -xc -c -o /tmp/gcccheck -
 
 succeeds.
 
 So this change to the configure script fixes the package for me:

 The actual build never uses GCC in a pipe.
