the .pc file from cairo? this wizardry is hard to fix ...

thanks for the TLS poiter and the -r flag, it is thus a lazy symbol.

I tried to rebuild pixman (without any update) and I notice that the 
work/solaris9-sparc/build-isa-sparcv9/pixman-0.22.2/pixman/.libs/libpixman-1.so

already has that issue. I then changed the receipe to build with GCC 
instead of sun studio, but no fix.

This is ldd -r on Solaris sparc 10
ldd -r /opt/csw/lib/libpixman-1.so
         libm.so.1 =>     /lib/libm.so.1
         libc.so.1 =>     /lib/libc.so.1
         /platform/SUNW,SPARC-Enterprise-T5220/lib/libc_psr.so.1
         libm.so.2 =>     /lib/libm.so.2


this on 9:ldd -r  /opt/csw/lib/libpixman-1.so
         /usr/lib/secure/s9_preload.so.1
         libm.so.1 =>     /usr/lib/libm.so.1
         libc.so.1 =>     /usr/lib/libc.so.1
         libdl.so.1 =>    /usr/lib/libdl.so.1
         /usr/platform/SUNW,SPARC-Enterprise-T5220/lib/libc_psr.so.1
         symbol not found: __tls_get_addr 
(/opt/csw/lib/libpixman-1.so)


I notice there is an extra "dl" library!

Darn. I found of several people who have a similarproblem, but 
absolutely no solution. some peoplce cited the -z linker flag, but it 
needs an option which I don't know which is correct.
