tinyx build problem

Today I tried to build tinyx. Accroding to the INSTALL.txt I've to build ncurses first.
This "ncruses" is very hard to compile, I met problems, such as:

make[2]: Entering directory `/mnt/tmp/study/tinyx/ncurses-5.5/Ada95/gen'
./gen '' B A >Character_Attribute_Set_Rep
./gen: error while loading shared libraries: /mnt/tmp/study/tinyx/ncurses-5.5/lib/libncurses.so.5: ELF file OS ABI invalid

Any way, after make, I found these's libcurses.so.xxx. then I tried to make install, ignore that error. Then I finished compile the tinyx. Here I gonna place some detail infomation about build tinyx
