There are a number of modules on CPAN that handle this.  Many are simply 
implemented using perl arrays and the tr// operator - hence they involve 
no XS coding at all.  Some allow for choosing and/or setting various 
codepages.  For example:

  http://www.cpan.org/authors/id/CXL/
  http://www.cpan.org/authors/id/CXL/Convert-EBCDIC-0.06.tar.gz
    
Geoffrey Rommel has recently posted a couple of Convert::IBM390
modules to the CPAN.  Convert-IBM390-0.01 is an xs based module
(fast) and Convert-IBM390p-0.01 is a pure perl module (may be slower
but easier to install, particularly on platforms without C compilers).
I've not yet had a chance to try them out but folks are certainly welcome
to do so.  See:

  http://www.cpan.org/authors/id/G/GR/GROMMEL/
  http://www.cpan.org/authors/id/G/GR/GROMMEL/Convert-IBM390-0_01_tar.gz

See also:

  http://www.cpan.org/authors/Genji_Schmeder/
  http://www.cpan.org/authors/Genji_Schmeder/Convert-Translit-1.03.tar.gz

which was developed on a Mac (I do not know what EBCDIC codepages are
mentioned in RFC 1345 unfortunately).
