Try removing ld-linux.so.1 from /lib. Does the libc5 netpbm still work?
I predict that it won't.

You might want the SW71 libtiff-devel instead of SW81.

cd netpbm-10.31/converter/other/
make tifftopnm
make pnmtotiff

This might fail if you have not already built libnetpbm.so or .a with
'make' or 'make -k'.

There might be other programs which failed to build. You should
compare what you have with what is in the netpbm-libc5 package.

You can also install echo from slackware. It's probably in shutils.tgz.
The package may be larger, but the echo binary itself is smaller than
busybox.

_p.a is for profiling. Profiling is for C programmers who want to figure
out what part of their programs need to be optimized. The rest of us
can safely delete the libraries ending in _p.a.

A lot. Possibly an average of half a megabyte for each netpbm
program.

It does not make much sense to do this unless you use the 'merge' build
option for netpbm.

If you want BL2 users to not have to upgrade, then build with the SW71
libraries.

It is some kind of character set conversion. You usually do not need it if you
read English.

Maybe. Does loadfont work without it?

No.

I look forward to trying this new netpbm package out.
