Note that libpthread.a is provided by the libc6-dev package and does
not need to be installed by default, IIRC.
anarcat at xtanbul[/usr/lib]% dpkg-query -S libpthread.a
libc6-dev: /usr/lib/libpthread.a
anarcat at xtanbul[/usr/lib]%
Also, this package is not required by most applications. Only when you
install build tools, does the static lib gets installed.
I like the idea of splitting a port's library between static and
shared packages. Most end-users that don't need to compile anything
don't need static libraries. -dev packages also contain the header
files. I'd like to see the same in our ports system.
