I'd like to ask for your kind help with the installation of EPACTS. There is an error as follows when install the software:
Actually the GROFF software has been successfully installed, for example, the command "groff --version" works well (version 1..22.2). Does it mean the module "pfbtops" was not installed? If that's the case, how can I install the specific module of "pfbtops"? I tried different methods to deal with this problem, such as installing different version of GROFF, but it still failed. My linux system is Red Hat 4.8.5-28.
Many thanks and looking forward to your kind reply.
