Tk/Tcl extensions: error while compile BLT

I am compile BLT under OS X 10.10.5, while I make after ./configure, some error occur here: 

FDSM_lhn@Nirvana:~/Downloads/blt2.4z$ sudo make -I/opt/X11/include

make[1]: *** [bltAlloc.o] Error 1
make: *** [all] Error 2

What should I do to avoid this?

You're working with an elderly codebase, so some surgery is required. Alas.

The four offending declarations in bltNsUtil.h need to be removed as Tcl now declares them properly; Tcl_FindCommand, Tcl_CreateNamespace, Tcl_FindNamespace and Tcl_Export are part of Tcl's public API and have been for years. (The problem declarations are on lines 50, 67, 72, and 75, plus probably one or two lines further in each case.)

Also, you're recommended to not use sudo while doing the build itself, but rather just when doing the install afterwards. Mere compilation of the code shouldn't require elevated permissions.
