	The version on AUR seems to still be for 0.37 (and I still get the 
build error, pasted below). Did you mean to attach an updated PKGBUILD?

The error (which is fixed by adding -fPIC to Makefiles in btparse):
=====
Running Mkbootstrap for Text::BibTeX ()
chmod 644 BibTeX.bs
rm -f blib/arch/auto/Text/BibTeX/BibTeX.so
cc  -shared -march=x86-64 -mtune=generic -O2 -pipe -L/usr/local/lib 
-fstack-protector BibTeX.o btxs_support.o  -o 
blib/arch/auto/Text/BibTeX/BibTeX.so btparse/src/.libs/libbtparse.a\
                 \

/usr/bin/ld: btparse/src/.libs/libbtparse.a(input.o): relocation
