ps2pdf is not working anymore - Macport upgrade on MacOS High Sierra 10.13.5

After an upgrading following a break dependency on my MacOS High Sierra 10.13.5, the command “ps2pdf” doesn’t work anymore.

I use it with latex to convert a ghostscript file .ps, generated from latex compiler and dvips command.

Here is below the error I get with ps2pdf : $ ps2pdf file.ps

While reading gs_ll3.ps:
Error: /undefinedresource in findresource

A solution is to use instead pstopdf but this binary doesn’t produce href URL link on pdf generated output file : that’s why I would like to make work the classical binary ps2pdf.

I tried to uninstall ghostscript macport and reinstall it but this doesn’t change anything.

I have also tried with pdflatex but there are some errors too :
