FreeBSD - Port p5-Encode-Detect error

While patching one of the FreeBSD box, a perl module port, converters/p5-Encode-Detect-1.01, failed to compile. This is the abstract of the error message :

Stop in /usr/ports/converters/p5-Encode-Detect.

It seems like the port devel/p5-ExtUtils-CBuilder didn't quite compile it's option and installed properly. Reinstalling devel/p5-ExtUtils-CBuilder didn't help. Re-compile all of the dependency of converters/p5-Encode-Detect & devel/p5-ExtUtils-CBuilder also didn't work as well.

The error message does strongly suggest that there's problem with devel/p5-ExtUtils-CBuilder. It's time to get my hands dirty, by manually compiling the port devel/p5-ExtUtils-CBuilder :

1. Go into the port devel/p5-ExtUtils-CBuilder :
   

   cd /usr/port/devel/p5-ExtUtils-CBuilder

2. Clean up the files previously compiled :
   

   make clean

3. Unpack the program into the ports directory :
   

   make extract

4. Enter the working directory :
   

   cd work

5. Prepare the make file for this perl module :
   

   perl Makefile.PL

6. Compile this perl module using ports :
   

   make

At the end of this compile, there's a error messages :

Warning: prerequisite IPC::Cmd 0 not found.

Ah ha, another perl module is needed but this port didn't make it as a dependency.


Searching through the ports and found this needed perl module, devel/p5-IPC-Cmd :

make quicksearch name=ipc-cmd

Install the devel/p5-IPC-Cmd port, to fulfill the dependency :

portupgrade -Nv devel/p5-IPC-Cmd

After finishing installing the devel/p5-IPC-Cmd port, proceed to install devel/p5-ExtUtils-CBuilder :

portupgrade -vr devel/p5-ExtUtils-CBuilder

Since all compile fine, continue the patching :

portupgrade -var

Voilla !!!
