I tried this to the users list yesterday, but didn't see it in the
archives.
Anyway, this is sort of following up to an older openssl-dev article
since i'm having a similar problem, and don't quite understand the
response in:
http://www.mail-archive.com/[email protected]/msg09258.html
Since there were no further followups...

Dr Stephen N. Henson responded:
They are different and incompatible formats, that's expected
behaviour. The RSA_PUBKEY variant may be preferable because it's
more standard and is extendible to non-RSA algorithms.
My questions:
- Does this mean that the PEM_write_XXX and PEM_read_XXX routines
are not 'inverses' of each other?
- What routines should one be using to read the public key back?
Should we be using the i2d_xxx routines directly or something else?
