There are a few problems with this...

1) The "or" operator is meant to connect two boolean expressions,
   so instead of
      name() = pubdate or dc:date
   you want
      name() = pubdate or name() = dc:date

2) pubdate needs to be quoted; otherwise it is interpreted as
   "the string value of the child element of . whose name is 'pubdate'"
   so you want
      name() = 'pubdate' or name() = 'dc:date'
   or
      self::pubdate or self::dc:date

   The latter form has the benefit of doing proper namespace checking.
   (Assuming you've declared the dc namespace in your stylesheet.)

You were on the right track...

<xsl:if test="self::pubdate or self::dc:date">
  <xsl:element name="pubdate">
    <xsl:value-of select="." />
  </xsl:element>
</xsl:if>
