May be with modification of xmlsec code to return ltdl error message 
diagnose will be simpler.
Lets check following part of code (dl.c):
====
xmlSecError(XMLSEC_ERRORS_HERE,
                     NULL,
                     "lt_dlinit",
                     XMLSEC_ERRORS_R_IO_FAILED,
                     XMLSEC_ERRORS_NO_MESSAGE);
=====
XMLSEC_ERRORS_NO_MESSAGE is a macro that return " " .
It cannot be replaced by lt_dlerror() as function may return NULL and of 
solaris (10 until .....) xxxprintf will crash.
So a new function is required as example:
========
static const char * xmlsec_lt_dleror(void);

const char * xmlsec_lt_dleror() {
    const char *s = lt_dlerror();
    return s ? s : XMLSEC_ERRORS_NO_MESSAGE;
}
=========
and to replace XMLSEC_ERRORS_NO_MESSAGE with xmlsec_lt_dleror()

May be you could post issue to libtool list, i.e. authors .

Just for protocol , could you post version of ltdl.
