Building with -MCPAN but cannot find libraries

mldvx4 has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying add Image::Scale manually using -MCPAN, but get an error in that the installation process cannot find the installed libraries:

# perl -MCPAN -e shell
[download]

Once in the shell, I try to install the module:

cpan[1]> install Image::Scale
Reading '/root/.cpan/Metadata'

Failed during this command:

The system seems to have the libraries installed:

$ find / -type f \( -name 'libpng*' -o -name 'libjpeg*' \) -print
/usr/lib/libpng16.so.16.37.0
/usr/lib/libjpeg.so.8.2.2
/usr/lib/libpng16.a
[download]

What steps have I missed or gotten wrong?

You also need to install the libraries' header files (e.g. /usr/include/libpng16/png.h or whatever your system uses). They are usually located in devel packages, i.e. libpng-devel-. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]`	[reply] [d/l]

Thanks! I appreciate it. I succeeded now after adding the development packages for libpng, etc. I also had to add `perl-dev` and `musl-dev`. `% perl -MImage::Scale -e 'exit' % echo $? 0` [download]	[reply] [d/l] [select]
