As previously mentioned, that's just natural for .a libraries :) I think libtool is supposed to record this "discrepancy" into the .la files it generates, and at the end of the way, when a program is linked against mylib.la, it will finally pull in the boost.a - in the last stage mind ye, when one is about to produce the program, the one spot where non-PIC is ok.
