Hmmm, I created a copy of /usr/lib/pkgconfig/gts.pc, changed it to look 
like this:
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: GTS
Description: GNU Triangulated Surface Library
Version: 0.7.6
Requires: glib-2.0
Libs: -L${libdir}  -lgts -lm
Cflags: -I${includedir}

and put it in a directory before /usr/lib/pkgconfig in the 
PKG_CONFIG_PATH environment variable. Now I have:
pkg-config gts --libs
-lgts -lm -lglib-2.0
gts-config --libs
-L/usr/lib -lgts -lglib-2.0 -lm

which are equivalent, as pkg-config always strips -L/usr/lib

Running scons now works fine, so do the demos. lildolfin.so is no longer 
linked with gthreads, the -pthreads flag is also gone.

Hope this helps.
