Thanks for implementing my suggested changes to the pcx package.
The worrisome thing about the PCx license terms is that they claim to
apply to derivative works. Also, I have hopes of my package being
included in Debian some day, which wouldn't be possible if it depended
on a non-free package.
My package doesn't run PCx in a script but calls the C library
functions directly. My best idea lately is to have it dlopen the
library if found but otherwise run without it, which I hope wouldn't
defy either Debian policy or copyright law.
The pcx package could be distributed separately from mine by Debian as
you recommend, but I'll need a dynamic library (because the static
library libPCx.a can't be dlopened). This patch to debian/rules makes
it build one, with the PCx executable binary remaining statically
linked. (The PCx build script appears to ignore the CFLAGS environment
variable but observes CC and FC.)

I also had to make some changes to postinst and prerm to create and
remove the symbolic link correctly, even though I thought that's what
dh_makeshlibs and/or ldconfig were for.

I would be very appreciative if you made these further changes to the
package.
Best regards,
